NAME
tin, rtin - Usenet newsreader

SYNOPSIS
tin [[-h|-H|-V] | [[-a] [-dlnq|-Q] [-ACkrTzxX]] [[-R|-S] -s News_dir]
[-cuvZ] [-4|-6] [-o|-w|-N|-M address] [-D debug_level] [-G arti-
cle_limit] [-f newsrc_file] [-g server[:port]] [-m Mail_dir] [-p port]
[-t timeout] [-I index_dir] [newsgroup[,...]]]

DESCRIPTION
tin is a full-screen easy to use Usenet newsreader. It can read news
locally (e.g., /var/spool/news) or remotely (rtin or tin -r option) via
an NNTP (Network News Transport Protocol, RFC3977) or NNTPS (RFC8143)
server. It will automatically utilize NOV newsoverview(5) style index
files if available locally or via the NNTP [X]OVER command (RFC2980,
RFC3977).

tin has four separate levels of operation: Selection level, Group
level, Thread level and Article level. Use the Help ('h') command to
view a list of the commands available at a particular level.

On startup tin will show a list of the newsgroups found in ${TIN_HOME-
DIR:-"$HOME"}/.newsrc. An arrow '->' or highlighted bar will point to
the first newsgroup. Move to a group by using the terminal arrow keys
(terminal dependent) or Down ('j') and Up ('k'). Use PgUp/PgDn (termi-
nal dependent) or PageUp ('^U') (CTRL-U) and PageDown ('^D') (CTRL-D)
to page up/down. Enter a newsgroup by pressing '<CR>'.

The GroupNextUnreadArtOrGrp ('<TAB>') key enters the next newsgroup
with unread articles.

EXIT STATUS
0 Successful program execution. No unread news available in batch
mode.

1 Usage, syntax, configuration file or network error.

2 Unread news available (batch mode (''-Z'') only).

3 NNTP error.

OPTIONS
-4 Force connecting via IPv4 to the remote NNTP server. Only
available when built with IPv6 support.

-6 Force connecting via IPv6 to the remote NNTP server. Only
available when built with IPv6 support.

-a Toggle ANSI color (default is off).

-A Force authentication on initial connect. Only available
when reading via NNTP.

-c Create/update index files for every group in ${TIN_HOME-
DIR:-"$HOME"}/.newsrc or file specified by the ''-f'' op-
tion and mark all articles as read.

-C Use COMPRESS NNTP extension (RFC8054) if available. See
also nntp_read_timeout_secs, '-t'' and the "SECURITY" and
"BUGS" section.

-d Don't load newsgroup descriptions and servers message of
the day (interactive mode).

-D debug-level
Enter debug-level (1 = NNTP, 2 = filter, 4 = newsrc, 8 =
threading, 16 = memory, 32 = attributes, 64 = misc, 128 =
remove existing debug files). For NNTP-level ''-v'' con-
trols the verbosity of the output. Depending on the debug-
level various files may be written to $TMPDIR and/or on
screen output may be given. See also the "SECURITY" sec-
tion!

-f file Use the specified file of subscribed to newsgroups in place
of ${TIN_HOMEDIR:-"$HOME"}/.newsrc.

-g server[:port]
Use the server[:port] and newsrc specified in ${TIN_HOME-
DIR:-"$HOME"}/.tin/newsrctable. Only available when reading
via NNTP.

-G article-limit
Limit the number of articles/group to retrieve from the
server. If article-limit is > 0 not more than the last ar-
ticle-limit articles/group are fetched from the server. If
article-limit is < 0 tin will start fetching articles from
your first unread minus absolute value of article-limit.
Default is 0, which means no limit.

-h Help listing all command-line options.

-H Brief introduction to tin that is also shown the first time
it is started.

-I dir Directory in which to store newsgroup index files. Default
is ${TIN_INDEX_NEWSDIR:-"${TIN_HOME-
DIR:-"$HOME"}/.tin"}/.news. This option has no effect if
tin retrieves its index files via NNTP and cache_over-
view_files is turned off.

-k Skip the certificate verification step for NNTPS connec-
tions and proceed without checking. This option implies
''-T''. See also the "SECURITY" section.

-l Get number of articles per group from the ${TIN_LIB-
DIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active} file. If read-
ing via NNTP this is done with the LIST command (RFC3977).
This might result in incorrect article counts but is usu-
ally faster than the default which is to read the
${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active} file
(either directly or via LIST) and then check the article
count via NNTP GROUP command (RFC3977) ''-ln''. If reading
via NNTP and LIST COUNTS (RFC6048) is available that is
used instead as it gives more accurate article counts.

-m dir Mailbox directory to use. Default is ${TIN_HOME-
DIR:-"$HOME"}/Mail.

-M user Mail unread articles to specified user for later reading.
For more information read section "AUTOMATIC MAILING AND
SAVING NEW NEWS".

-n Only load groups from the ${TIN_LIBDIR:-NEWSLIB-
DIR}"/"${TIN_ACTIVEFILE:-active} file that are subscribed
to in the user's ${TIN_HOMEDIR:-"$HOME"}/.newsrc. This al-
lows a noticeable speedup when connecting via a slow line,
but tin may not be able detect which groups are moderated.
See also ''-l''.

-N Mail unread articles to yourself for later reading. For
more information read section "AUTOMATIC MAILING AND SAVING
NEW NEWS".

-o Quick post all postponed articles and exit. In order for
this to be really quick, it should be used with ''-n'' if
possible.

-p port Port to use if reading via NNTP (default is 119 or 563 if
NNTPS is enabled, see ''-T''). This also overrides the en-
vironment variable $NNTPPORT if set. Only available when
reading via NNTP.

-q Don't check for new newsgroups and skip loading the servers
message of the day.

-Q Quick start. Start tin as quickly as possible. Currently
this is equivalent to ''-dnq''. See also the ''-C'' and
''-G'' command-line options.

-r Read news remotely from the default NNTP server specified
in the environment variable $NNTPSERVER or contained in the
file /etc/nntpserver.

-R Read news saved by the ''-S'' option.

-s dir Save/read articles to/in directory. Default is ${TIN_HOME-
DIR:-"$HOME"}/News.

-S Save unread articles for later reading by the ''-R'' op-
tion. For more information read section "AUTOMATIC MAILING
AND SAVING NEW NEWS".

-t timeout Override the nntp_read_timeout_secs setting. Default is 120
seconds, allowed maximum is 16383.

-T Enable NNTPS (NNTP over TLS). This also overrides the envi-
ronment variable $NNTPPORT if set. Only available when
reading via NNTP.

-u Create/update index files for every group in ${TIN_HOME-
DIR:-"$HOME"}/.newsrc or file specified by the ''-f'' op-
tion. This option is disabled if tin retrieves its index
files via an NNTP server and cache_overview_files is turned
off.

-v Verbose mode for ''-c'', ''-D'', ''-M'', ''-N'', ''-S'',
''-u'' and ''-Z'' options. Can be used multiple times to
increase verbosity.

-V Print version information and compilation options.

-w Quick mode to post an article and then exit. This option
implies ''-d''. In order for this to be really quick, it
should be used with ''-n'' if possible.

-x No-posting mode. You cannot post articles if you use this
option.

-X No overwrite mode. ${TIN_HOMEDIR:-"$HOME"}/.newsrc and
files in ${TIN_HOMEDIR:-"$HOME"}/.tin will not be overwrit-
ten but may be created if they don't exist.

-z Only start tin if there is any new/unread news. If there is
news tin will position cursor at first group with unread
news. Useful for putting in login file.

-Z Check if there is any new/unread news and exit with appro-
priate status. If ''-v'' option is specified the number of
unread articles in each group is printed. An exit code 0
indicates no news, 1 that an error occurred and 2 that
new/unread news exists. Useful for writing scripts.

tin can also dynamically change its options by the OptionMenu ('M')
command. Any changes are written to ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc.
For more information see section "GLOBAL OPTIONS MENU AND TINRC CONFIG-
URABLE VARIABLES" and tin(5).

A list of groups can be specified after the other command-line options.
This can be useful if you wish to yank in or subscribe to a hand-picked
subset of the active newsgroups. See the section "NEWSGROUP LISTS &
WILDCARDS" for the types of pattern that tin understands.

If you specify a single group-name, or a wildcard that matches a single
group, then you will automatically enter that group. Otherwise the nor-
mal group selection screen will appear, but with all the matching
groups present too, as though you had yanked just those groups in.

With the ''-w'' flag a given group-name is used as default group to
post to. If more than one group or a wildcard is specified only the
first group respectively the first group that matches is used.

Once you use SelectYankActive ('y') to yank in all active groups, or
SelectToggleReadDisplay ('r') to toggle the read/unread status, then
the command-line groups will be gone. You can use SelectSyncWithActive
('Y') to reread the ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-ac-
tive} file and get them back.

NB: With the ''-n'' flag, only unsubscribed groups in the ${TIN_HOME-
DIR:-"$HOME"}/.newsrc file (or the newsrc-file given by the ''-f'' com-
mand-line switch or via ${TIN_HOMEDIR:-"$HOME"}/.tin/newsrctable) can
be matched.

Command-line options have higher priority than attributes and tinrc op-
tions. Thus, command-line option takes precedence over configured val-
ues.

USAGE
NEWS ADMINISTRATION
Maintaining Netnews on large networks of machines can be a pretty time
consuming job as I discovered when I was given the job of maintaining
our news system and news users.

A user starting tin for the first time can be automatically subscribed
to a list of newsgroups that are deemed appropriate by the news admin-
istrator. The subscriptions file should be created in your news lib di-
rectory (i.e., ${TIN_LIBDIR:-NEWSLIBDIR}/subscriptions) and should be
world readable. If you read news via NNTP, then your news server must
support the LIST SUBSCRIPTIONS command. It is part of the NNTP List Ex-
tensions (RFC6048) and all modern servers should understand it.

SCREEN FORMAT
tin has four separate levels of operation: Selection level, Group
level, Thread level and Article level.

At the Selection level the title displays (the name of the news server
(with a "[T]"- or "[k]"-suffix if reading via NNTPS (insecurely)) and)
the number of subscribed groups (containing new unread articles). The
newsgroups are displayed in the middle of the screen usually with the
number of unread articles displayed on the same line in front, but it
can be customized via select_format.

There may also be a character prefixing the line. An explanation fol-
lows:

u This group is unsubscribed. To see only your subscribed
groups use the SelectToggleReadDisplay ('r') or SelectYankAc-
tive ('y') toggle keys.

M This is a moderated group. Any posts you make will have to be
approved by the group administrator before it will be made
public. tin will ask for confirmation before you post to a
moderated group.

N This is a new newsgroup which has been created since you last
used tin. New newsgroups are not subscribed to by default
(However, see the $AUTOSUBSCRIBE / $AUTOUNSUBSCRIBE environ-
ment variables). Subscribe to it in the normal way if you
wish the group to continue to appear in your Selection Menu.
Simply ignore new newsgroups and they will be gone the next
time you start tin. You will have to yank in all the groups
to find them in a later session.

D This group no longer exists. If you no longer wish to see
this group then unsubscribe from it in the normal way. This
flag will only appear if you have set strip_bogus to "ask" in
the Options Menu.

X You may no longer make posts to this group. Often a group
will be superseded by a more appropriately named one.

= This group has been renamed and you may no longer post to it.
If you do, then you will receive an error from your news
server telling you the correct group to post to.

At the Group level the title contains the name of the group, the number
of conversation threads, the abbreviated threading method (thread_arti-
cles), the limit of articles to get (if set; getart_limit), the total
number of (unread) articles (art_marked_read or art_marked_unread), the
number of hot articles art_marked_selected, the number of read hot ar-
ticles (if any; art_marked_read_selected), the number of recent arti-
cles (art_marked_recent) and the number of killed articles
(art_marked_killed). I.e.:

alt.sources (5B -50/23+ 0* 3o 0K)

The characters after the numbers are depending to the configuration and
if your are in show_only_unread_arts mode or not. Some numbers could be
missing if the specific option is not enabled. It might also contain an
'M', 'X' or '=' (see above; doesn't work with the ''-n'' command-line
switch!) if the group is moderated, set to no posting or postings to it
get redirected.

If a thread has unread articles it is marked with art_marked_unread in
front of the total number of articles in the thread. If there are re-
cent articles within the thread it might be marked with art_marked_re-
cent in front of the total number of articles in the thread -- this is
controlled by the recent_time option. If a thread has hot articles in
it (see also section "FILTERING ARTICLES") it's marked with
art_marked_selected in front of the total number of articles in the
thread. The display can be customized via group_format.

COMMON EDITING COMMANDS
An emacs(1) style editing package allows the easy editing of input
strings. A history list allows the easy reuse of previously entered
strings. In addition to the cursor keys, the following commands are
available when editing a string:

^A, ^E move to beginning or end of line, respectively.

^F, ^B non-destructive move forward or back one location, respec-
tively.

^D delete the character currently under the cursor, or send EOF
if no characters in the buffer.

^H, <DEL> delete character left of the cursor.

^K delete from cursor to end of line.

^P, ^N move through history, previous and next, respectively.

^L, ^R redraw the current line.

<CR> places line on history list if non-blank, appends newline and
returns to the caller.

<ESC> aborts the present editing operation.

GLOBAL COMMANDS
The following commands are available at all 4 menu levels and always
have the same effect.

ShellEscape '!'
Shell escape. ShellEscape by itself will launch a shell,
ShellEscape <command> will run an external <command>. This
facility may have been disabled by the System Administrator.

ToggleColor '&'
Toggle use of ANSI color.

RedrawScr '^L'
Redraw the current screen.

ScrollUp '<'
Scroll screen up by one line.

ScrollDown '>'

postpone-menu offers the following actions: PromptYes ('y') =
reload and spawn editor; PostponeOverride ('Y') = post arti-
cle (without spawning editor); PostponeAll ('A') = post all
postponed articles (without spawning editor); PromptNo ('n')
= skip this article; Quit ('q') = quit postponed menu. Cur-
rently there is no 'simple' way to delete a postponed article
from the postponed-file, you have to use the following com-
mand sequence instead: reload it with Postponed, enter editor
with PromptYes, quit editor, discard posting with Quit
('^O''y''q'). See also ''-o'' command-line switch.

Help 'h' Help screen of commands available on the current menu. You

GLOBAL OPTIONS MENU AND TINRC CONFIGURABLE VARIABLES
At startup, tin reads in the configuration files (see also tin(5)).
They contain a list of variables that can be used to configure the way
tin works. If it exists, the global configuration file, /etc/tin/tinrc
is read. After that, the user's own configuration file is read from
${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc. The global file is useful for dis-
tributing system-wide defaults to new users who have no private tinrc
yet.

The variables are user configurable by editing ${TIN_HOME-
DIR:-"$HOME"}/.tin/tinrc directly. Most of them can also be set in the
GLOBAL OPTIONS MENU which is accessed by pressing OptionMenu ('M') at
all levels. It allows the user to customize the behavior of tin. The
options are saved to the file ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc when
you exit tin so don't edit the file directly whilst tin is running.

In the options menu use the cursor keys in the usual way to move
around. Use ConfigSelect ('^J' or '<CR>') to 'open' the option you wish
to change. You will need to enter a new value or use '<SPACE>' to tog-
gle the available options. ConfigSelect will save the new value,
'<ESC>' will abort without saving changes.

As with the other menus, RedrawScr ('^L') will redraw the screen. You
can use SearchSubjF ('/'), SearchSubjB ('?') and SearchRepeat ('\') to
search for a specific option. Use Quit ('q') to exit the option menu
and keep your changes. Use QuitTin ('Q') to exit without keeping your
changes.

The options menu provides access to the attributes menu for the current
group by the ConfigToggleAttrib ('<TAB>') command. Pressing ConfigTog-
gleAttrib again toggles back to the options menu. For more information
see section "ATTRIBUTES MENU AND GROUP ATTRIBUTES".

The ConfigScopeMenu ('S') command brings up the scopes menu. For more
information see section "SCOPES MENU".

Here is a full list of all the available variables. The name in braces
is the name of the corresponding setting in ${TIN_HOME-
DIR:-"$HOME"}/.tin/tinrc.

A regular expression that will be applied when reading articles.
All matching lines are shown in col_extquote. If extquote_regex is
blank, then tin uses a built-in default.

Force redraw after certain commands (force_screen_redraw)
Specifies whether a screen redraw should always be done after cer-
tain external commands. Default is OFF.

Number of articles to get (getart_limit)
If getart_limit is > 0 not more than the last getart_limit arti-
cles/group are fetched from the server. If getart_limit is < 0 tin
will start fetching articles from your first unread minus absolute
value of getart_limit. Default is 0, which means no limit.

Catchup group using left key (group_catchup_on_exit)
If ON catchup group when leaving with the left arrow key. Default
is ON.

Format string for the Group level (group_format)
Format string tin uses for Group level representation. See the sec-
tion "CUSTOMIZING THE SCREEN FORMAT". Default is
"%n %m %R %L %s %F".

Go to the next unread article with (goto_next_unread)
Which keys tin should accept to jump to the next unread article.
Possible is any combination of PageDown and PageNextUnread. When
PageDown is set tin jumps to the next article at the end of the
current one. When PageNextUnread is set tin jumps immediately to
the next article when PageNextUnread ('<TAB>') is pressed. Default
is PageNextUnread.

Display uue data as an attachment (hide_uue)
If set to 'No' then raw uuencoded data is displayed. If set to
'Yes' then sections of uuencoded data will be shown with a single
tag line showing the size and filename (much the same as a MIME at-
tachment). If set to 'Hide all' then any line that looks like
uuencoded data will be folded into a tag line. This is useful when
uuencoded data is split across more than one article but can also
lead to false positives. This setting can also be toggled in the
article viewer. Default is 'No'.

External inews (inews_prog)
Path, name and options of external inews(1). If you are reading
via NNTP the default value is "--internal" (use built-in NNTP in-
ews), else it is "inews -h". The article is passed to inews_prog on
STDIN via '< article'.

(info_in_last_line)
If ON, show current group description or article subject in the
last line (not in the pager and global menu) -- ToggleInfoLastLine
('i') toggles setting. This facility is useful as the full width of
the screen is available to display long subjects. Default is OFF.

Use interactive mail reader (interactive_mailer)
Interactive mailreader: if greater than 0 your mailreader will be
invoked earlier for reply so you can use more of its features (e.g.
MIME, pgp, ...). 1 means include headers, 2 means don't include
headers (old use_mailreader_i=ON option). 0 turns off usage. This
option has to suit mailer_format. Default is 0.

Use inverse video for page headers (inverse_okay)
If ON use inverse video for page headers and URL highlighting. De-
fault is ON.

Keep failed arts in ~/dead.articles (keep_dead_articles)
If ON keep all failed postings in ${TIN_HOMEDIR:-"$HOME"}/dead.ar-
ticles besides keeping the last failed posting in ${TIN_HOME-
DIR:-"$HOME"}/dead.article. Default is ON.

Filter which articles (kill_level)
This option controls the processing and display of articles that
are killed. There are 3 options:

0 Kill only unread arts is the 'traditional' behavior of tin.
Only unread articles are killed once only by marking them read.
As filtering only happens on unread articles with kill_level
set to 0, art_marked_killed and art_marked_read_selected are
only shown once. When you reenter the group the mark will be
gone.

1 Kill all arts & show with K will process all articles in the
group and therefore there is a processing overhead when using
this option. Killed articles are threaded as normal but they
will be marked with art_marked_killed.

2 Kill all arts and never show will process all articles in the
group and therefore there is a processing overhead when using
this option. Killed articles simply does not get displayed at
all.
Default is 0 (Kill only unread arts).

Use 8bit characters in mail headers (mail_8bit_header)
Allows 8bit characters unencoded in the header of mail message. De-
fault is OFF. Turning it ON is effective only if mail_mime_encoding
is also set to 8bit. Leaving it OFF is safe for most users and com-
pliant to Internet Mail Standard (RFC5322 and RFC2047). Default is
OFF.

Mail address (mail_address)
User's mail address (and full name), if not username@host. This is
used when creating articles, sending mail and when pgp(1) / gpg(1)
signing (RFC4880).

MIME encoding in mail messages (mail_mime_encoding)
MIME encoding of the body in mail message, if necessary (8bit,
base64, quoted-printable, 7bit). Default is quoted-printable.

Quote line when mailing (mail_quote_format)
Format of quote line when replying (via mail) to an article (%A=Ad-
dress, %D=Date, %F=Fullname+Address, %G=Groupname, %M=Message-ID,
%N=Fullname, %C=Firstname, %I=Initials). Default is "In article %M
you wrote:"

Format of the mailbox (mailbox_format)
Select one of the following mailbox-formats: MBOXO (default, except
on SCO), MBOXRD or MMDF (default on SCO). See mbox(5) and RFC4155
for more details on MBOXO and MBOXRD and mmdf(5) for more details
about MMDF.

Mail directory (maildir)
The directory where articles/threads are to be saved in mbox(5)
format. This feature is mainly for use with the mutt(1) mail pro-
gram. It allows the user to save articles/threads/groups simply by
giving '=' as the filename to save to. Default is ${TIN_HOME-
DIR:-"$HOME"}/Mail.

Invocation of your mail command (mailer_format)
The format string used to create the mailer command with parameters
that is used for mailing articles to other people. Default is '%M
"%T" < %F' (e.g., /bin/mail "iain" < ~/.article). The flexible for-
mat allows other mailers with different command line parameters to
be used such as
sendmail -oem -t < %F
mutt -s "%S" -- "%T" < %F
mutt -H %F
claws-mail --compose "mailto:%T?subject=%S&insert=%F"
interactive_mailer must be set adequate. The following substitu-
tions are supported:
%F filename
%M default_mailer
%S subject-field
%T to-filed
%U username
%% %

'Mark as (un)read' ignores tags (mark_ignore_tags)
When this is ON, the GroupMarkThdRead ('K'), ThreadMarkArtRead
('K'), MarkThdUnread ('Z') at Group level and MarkArtUnread ('z')
at Thread level functions mark just the current article or thread,
ignoring other tagged, (un)read articles. When OFF, the same func-
tion presents a menu with choices of the current thread or article,
all tagged, unread articles, or nothing.

Mark saved articles/threads as read (mark_saved_read)
If ON mark articles that are saved as read. Default is ON.

Viewer program for MIME articles (metamail_prog)
Path, name and options of external metamail(1) program used to view
non-textual parts of articles. To use the built-in viewer, set to
--internal. This is the default value when metamail(1) is not in-
stalled. Leave it blank if you don't want any automatic viewing of
non-textual attachments. The PageViewAttach ('V') command can al-
ways be used to manually view any attachments. See also
ask_for_metamail.

MM_CHARSET (mm_charset)
Charset supported locally, which is also used for MIME header
(charset parameter and charset name in header encoding) in mail and
news postings. If MIME_STRICT_CHARSET is defined at compile time,
text in charset other than the value of this parameter is consid-
ered not displayable and represented as '?'. Otherwise, all charac-
ter sets are regarded as compatible with the display. If it's not
set, the value of the environment variable $MM_CHARSET is used. US-
ASCII or compile-time default is used in case neither of them is
defined. If your system supports iconv(3), this option is disabled
and you should use mm_network_charset instead.

MM_NETWORK_CHARSET (mm_network_charset)
Charset used for posting and MIME headers; replaces mm_charset.
Conversion between mm_network_charset and local charset (determined
via nl_langinfo(3)) is done via iconv(3), if this function is not
available on your system this option is disabled and you have to
use mm_charset instead. mm_network_charset is limited to one of the
following charsets:
US-ASCII, ISO-8859-{1,2,3,4,5,7,9,10,13,14,15,16}, KOI8-{R,U,RU}
EUC-{CN,JP,KR,TW}, ISO-2022-{CN,CN-EXT,JP,JP-1,JP-2}, Big5,
UTF-8
Not all values might work on your system, see iconv_open(3) for
more details. If it's not set, the value of the environment vari-
able $MM_CHARSET is used. US-ASCII or compile-time default is used
in case neither of them is defined.

Attribute of highlighting with _dash_ (mono_markdash)
Character attribute of words emphasized like _this_. It depends on
your terminal which attributes are usable. See also word_h_dis-
play_marks and word_highlight.

Attribute of highlighting with /slash/ (mono_markslash)
Character attribute of words emphasized like /this/. It depends on
your terminal which attributes are usable. See also word_h_dis-
play_marks and word_highlight.

Attribute of highlighting with *stars* (mono_markstar)
Character attribute of words emphasized like *this*. It depends on
your terminal which attributes are usable. See also word_h_dis-
play_marks and word_highlight.

Attribute of highlighting with -stroke- (mono_markstroke)
Character attribute of words emphasized like -this-. It depends on
your terminal which attributes are usable. See also word_h_dis-
play_marks and word_highlight.

(newnews)
These are internal timers used by tin to keep track of new news-
groups. Do not change them unless you understand what they are
for.

Display these header fields (or *) (news_headers_to_display)
Which news headers you wish to see. If you want to see _all_ the
headers, place an '*' as this value. This is the only way a wild-
card can be used. If you enter 'X-' as the value, you will see all
headers beginning with 'X-' (like X-Alan or X-Pape). You can list
more than one by delimiting with spaces. Not defining anything
turns off this option.

Do not display these header fields (news_headers_to_not_display)
Same as news_headers_to_display except it denotes the opposite. An
example of using both options might be if you thought 'X-' headers
were A Good Thing(tm), but thought Alan and Pape were miscreants...
well then you would do something like this: news_headers_to_dis-
play=X- news_headers_to_not_display=X-Alan X-Pape Not defining any-
thing turns off this option.

Quote line when following up (news_quote_format)
Format of quote line when posting/following up an article (%A=Ad-
dress, %D=Date, %F=Fullname+Address, %G=Groupname, %M=Message-ID,
%N=Fullname, %C=Firstname, %I=Initials). Default is "%F wrote:".

NNTP read timeout in seconds (nntp_read_timeout_secs)
Time in seconds to wait for a response from the server. Default is
120. Setting this to 0 means no timeout. As if you use the "-C"
option in conjunction with a low value for nntp_read_timeout_secs
may result in a timeout (and disconnect in batch mode) when con-
necting to large servers or entering large groups, because the
timer is set when the command is sent to the server and that needs
some time to compress the large response, the value should not be
set too small.

Unicode normalization form (normalization_form)
The normalization form tin should use to normalize unicode input.
The possible values are:

0 None: no normalization

1 NFKC: Compatibility Decomposition, followed by Canonical Compo-
sition

2 NFKD: Compatibility Decomposition

3 NFC: Canonical Decomposition, followed by Canonical Composition

4 NFD: Canonical Decomposition

5 NFKC_CF: Compatibility Decomposition, followed by Canonical
Composition and Case Folding
Some normalization modes are only available if they are supported by
the library tin uses to do the normalization. NFC should be used if
possible.

Use 8bit characters in news headers (post_8bit_header)
Allows 8bit characters unencoded in the header of a news article,
if set this also disables the generation of MIME-headers when they
are usually required. Default is OFF. Only enacted if post_mime_en-
coding is also set to 8bit. In a number of local hierarchies where
8bit characters are used, using unencoded (raw) 8bit characters in
header is acceptable and sometimes even recommended so that you
need to check the convention adopted in the local hierarchy of your
interest to determine what to do with this and post_mime_encoding.

MIME encoding in news messages (post_mime_encoding)
MIME encoding of the body in news message, if necessary. (8bit,
base64, quoted-printable, 7bit). Default is 8bit, which leads to no
encoding. base64 and quoted-printable are usually undesired on
usenet.

View post-processed files (post_process_view)
If ON, then tin will start an appropriate viewer program to display
any files that were post processed and uudecoded. The program is
determined using the mailcap(5) file. Default is ON.

Post process saved articles (post_process_type)
This specifies whether to perform post processing on saved arti-
cles. Because the shell archive may contain commands you may not

The character used in quoting included text to article followups
and mail replies. The '_' character represents a blank character
and is replaced with ' ' when read, %I is replaced by author's ini-
tials. Default is '>_'.

Quoting behavior (quote_style)
How articles should be quoted when following up or replying to
them. There are a number of things that can be done: empty lines
can be quoted, signatures can be quoted and quote_chars can be com-
pressed when quoting multiple times (for example, '> > >' will be
turned into '>>>'). The default is to compress quotes, and to quote
empty lines.
When you are viewing an article in raw mode ('^H'), and follow up
or reply to it, the signature will be quoted even if it would oth-
erwise not be. If show_signatures is off, then the signature will
never be quoted.

Regex used to show quoted lines (quote_regex)
A regular expression that will be applied when reading articles.
All matching lines are shown in col_quote. If quote_regex is blank,
then tin uses a built-in default.

Regex used to show twice quoted l. (quote_regex2)

Number of lines to scroll in pager (scroll_lines)
The number of lines that will be scrolled up/down in the article
pager when using cursor-up/down. The default is 1 (line-by-line).
Set to 0 to get traditional tin page-by-page scrolling. Set to -1
to get page-by-page scrolling where the top/bottom line is carried
over onto the next page. This setting supersedes
show_last_line_prev_page=ON. Set to -2 to get half-page scrolling.
This setting supersedes full_page_scroll=OFF.

Format string for the Selection level (select_format)

Show description of each newsgroup (show_description)
If ON show a short group description text after newsgroup name at
the group selection level. The ''-d'' command-line flag will over-
ride the setting and turn descriptions off. The text used is taken

following up to or replying to an article. If the path is a direc-
tory then the signature will be randomly generated from files that
are in the specified directory. If the path starts with a ! the
program the path points to will be executed to generate a signa-
ture. In order to pass the group name to the program, %G can be
specified. This will be replaced by the name of the current news-
group. --none will suppress any signature. Default is ${TIN_HOME-

Defines which threading method to use. It's possible to set the
threading type on a per group basis by setting the group attribute
variable thread_arts to 0 - 4 in the file ${TIN_HOME-
DIR:-"$HOME"}/.tin/attributes. (See also "GROUP ATTRIBUTES".) The
default is Both Subject and References. The choices are:

0 None, don't thread.

1 Subject, thread on ''Subject:'' only.

2 References, thread on ''References:'' only.

3 Both Subject and References, thread on ''References:'' then
''Subject:'' (default).

Suppress soft hyphens (suppress_soft_hyphens)
If ON remove soft hyphens in non verbatim blocks of articles in
UTF-8 when they are displayed in a UTF-8 locale. The character SOFT
HYPHEN (U+00AD) is an invisible format character that merely indi-
cates a preferred intraword line break position. However, some ter-
minal emulators display a space or a hyphen, for example, in the
place of the soft hyphen. This setting can be used to improve the
display of those articles. Default is OFF.

Regex used to highlight _underline_ (underscores_regex)
A regular expression that will be applied when reading articles.
All matching words are shown in col_markdash or mono_markdash. If
underscores_regex is blank, then tin uses a built-in default.

Program that opens URLs (url_handler)
The program that will be run when launching URLs in the article
viewer using PageViewUrl ('U'). The actual URL will be appended.
Default is url_handler.pl.

URL highlighting in message body (url_highlight)
Enable highlighting URLs in message body. Default is ON.

Use ANSI color (use_color)
If enabled tin uses ANSI-colors. Default is OFF.

Use scroll keys on keypad (use_keypad)
Default is OFF.

Use mouse in xterm (use_mouse)
Allows the mouse button support in an xterm(1x) to be enabled/dis-
abled. Default is OFF.

Use slrnface to show ''X-Face:''s (use_slrnface)
If enabled tin uses slrnface(1) to interpret the ''X-Face:''
header. For this option to have any effect, tin must be running in
an xterm(1x) and slrnface(1) must be in your $PATH. Default is OFF.

Use UTF-8 graphics (utf8_graphics)
If ON use UTF-8 characters for indicator ('->'), thread/attachment
tree and ellipsis ('...'). Default is OFF.

Regex for begin of a verbatim block (verbatim_begin_regex)
A regular expression that tin will use to find the begin of a ver-
batim block.

Regex for end of a verbatim block (verbatim_end_regex)
A regular expression that tin will use to find the end of a verba-
tim block.

Detection of verbatim blocks (verbatim_handling)
If ON verbatim blocks will be detected. Default is ON.

Wildcard matching (wildcard)
Allows you to select how tin matches strings. The default is 0 and
uses the wildmat(3) notation, which is how this has traditionally
been handled. Setting this to 1 allows you to use perl(1) compati-
ble regular expressions pcre(3) or pcre2(3) (see also perlre(1) and
pcrepattern(3) or pcre2pattern(3)). You will probably want to up-
date your filter file if you use this regularly. NB: Newsgroup
names will always be matched using the wildmat(3) notation.

What to display instead of mark (word_h_display_marks)
Should the leading and ending stars, slashes, strokes and dashes
also be displayed, even when they are highlighting marks?

0 no

1 yes, display mark

2 print a space instead

Word highlighting in message body (word_highlight)
Enable word highlighting. See word_h_display_marks for the options
available. If use_color is enabled the colors specified in
col_markdash, col_markslash, col_markstar and col_markstroke are
used for word highlighting else the character attributes specified
in mono_markdash, mono_markslash, mono_markstar and mono_markstroke
are used. Default is ON.

Page line wrap column (wrap_column)
Sets the column at which a displayed article body should be
wrapped. If this value is equal to 0, it defaults to the current
screen width. If this value is greater than your current screen
width the part off-screen is not displayed. Thus setting this op-
tion to a large value can be used to disable wrapping. If this
value is negative the wrap margin is the current screen width plus
the given value (as long as the result is still positive, otherwise
it will fall back to the current screen width). Default is 0, wrap-
ping at the current screen width.

Quote line when crossposting (xpost_quote_format)
Format is the same as for news_quote_format, this is used when an-
swering to a crossposting to several groups with no ''Fol-
lowup-To:'' set.

ATTRIBUTES MENU AND GROUP ATTRIBUTES
tin allows certain attributes to be set on a per group basis. If it ex-
ists, the global attributes file, ${TIN_LIBDIR:-NEWSLIBDIR}/attributes
is read. After that, the user's own attributes file ${TIN_HOME-
DIR:-"$HOME"}/.tin/attributes is read. The global attributes file is
useful for distributing system-wide defaults to new users who have no
private attributes file yet.

Note that the scope=<grouplist> line has to be specified before the at-
tributes are specified for that list. All attributes are set to a rea-
sonable default so you only have to specify the attribute that you want
to change (e.g., savedir). All toggle attributes are set by specifying
ON/OFF. Otherwise, these function exactly the same as their global
equivalents. For more details see tin(5).

Attributes can also be changed from the attributes menu which can be
accessed by ConfigToggleAttrib ('<TAB>') from the options menu or
ScopeSelect ('^J' or '<CR>') from the scopes menu. The attributes menu
looks and behaves very similar to the options menu. The title shows the
current scope. Attributes set in the current scope are marked with '+'
to the left of the attributes number.

Besides the keys for moving around and changing values known from the
options menu the attributes menu provides the following command: Confi-
gResetAttrib ('r') which resets an attribute to a default value.

SCOPES MENU
The scopes menu (accessible from the options menu with ConfigScopeMenu
('S')) shows all scopes read from the global and local attributes file.
Scopes from the global attributes file are marked with '!' to the left
of the scope number. Delete/rename/move are not possible with those
scopes.

In addition to the common moving keys the following commands are avail-
able: ScopeSelect ('^J' or '<CR>') enter the attributes menu for the
current scope, ScopeEditAttributesFile ('E') edit the local attributes
file, ScopeAdd ('a') add a new scope, ScopeDelete ('d') delete the cur-
rent scope, ScopeMove ('m') move the current scope to a new position,
ScopeRename ('r') rename the current scope. ToggleHelpDisplay ('H')
toggles the help mini menu at the bottom of the screen and posting eti-
quette after composing an article (beginner_level).

FILTERING ARTICLES
When there is a subject or an author which you are either very inter-
ested in, or find completely uninteresting, you can easily instruct tin
to auto-select or auto-kill articles that match rules that you specify.
This can be anything from the name of the author to the number of lines
in an article.

When tin starts up the user's kill-file ${TIN_HOME-
DIR:-"$HOME"}/.tin/filter (see also tin(5)) is read. Each time a news-
group is entered the rules are applied and articles killed or selected
when they meet certain criteria.

The degree to which rules are applied depend on the kill_level tinrc
setting. By default killed articles will only be marked read. Adjust
kill_level for more aggressive processing. Articles that match an auto-
selection rule are marked with a ''*''.

Filtering rules can be manually entered into ${TIN_HOME-
DIR:-"$HOME"}/.tin/filter (but don't do this whilst running tin else
you will lose your changes) or by using an on-screen menu within tin.

The filtering capabilities of tin have been significantly enhanced over
previous versions to include scoring and better pattern matching. It is
recommended that you read the file filtering in the tin documentation
directory. This file can also be read online at
<http://www.tin.org/filtering.txt>.

The on-screen filtering menu is accessed by pressing MenuFilterKill
('^K') or MenuFilterSelect ('^A') at the Group and Article levels. It
allows the user to kill or select an article that matches the current
''Subject:'' line, ''From:'' line or a string entered by the user. The
user entered string can be applied to the ''Subject:'' or ''From:''
line of an article. The filter can be limited to the current newsgroup
or it can apply to all newsgroups. Once entered the user can abort the
command and not save the new filter, edit the full filter file or save
filter.

POSTING ARTICLES
tin allows posting of articles, follow-up to already posted articles
and replying direct through mail to the author of an article.

Use the Post ('w') command to post an article to a newsgroup. After
entering the post subject the default editor (i.e., vi(1)) or the edi-
tor specified by the $VISUAL or $EDITOR environment variable will be
started and the article can be entered. To crosspost articles simply
add a comma and the name of the newsgroup(s) to the end of the ''News-
groups:'' line at the beginning of the article. After saving and exit-
ing the editor you are asked if you wish to a)bort posting the article,
e)dit the article again or p)ost the article to the specified news-
group(s).

Use the DisplayPostHist ('W') command to display a history of the arti-
cles you have posted. The date the article was posted, which newsgroups
the article was posted to and the articles subject line are displayed.
See the section "POSTING HISTORY LISTING" for more information.

Use the PageFollowupQuote ('f'), PageFollowup ('F') or PageFol-
lowupQuoteHeaders ('^W') command to post a follow-up article to an al-
ready posted article. The PageFollowupQuote command will copy the text
of the original article into the editor. The PageFollowupQuoteHeaders
command will copy the text and all headers of the original article into
the editor. The editing procedure is the same as when posting an arti-
cle with the Post ('w') command.

Use the PageReplyQuote ('r'), PageReply ('R') or PageReplyQuoteHeaders
('^E') command to reply direct through mail to the author of an already
posted article. The PageReplyQuote command will copy the text of the
original article into the editor. The PageReplyQuoteHeaders command
will copy the text and all headers of the original article into the ed-
itor. The editing procedure is the same as when posting an article with
the Post ('w') command. After saving and exiting the editor you are
asked if you wish to abort sending the article via PostAbort ('a'),
edit the article again via PostEdit ('e') or send the article to the
author via PostSend ('s').

CUSTOMIZING THE ARTICLE QUOTE STRING
When posting a followup to an article or replying direct to the author
of an article via email the text of the article can be quoted. The be-
ginning of the quoted text can contain information about the quoted ar-
ticle (e.g., Name and the Message-ID of the article). To allow for dif-
ferent situations certain information from the article can be used in
the quoted string. The following variables are expanded if found in the
tinrc variables mail_quote_format, news_quote_format or
xpost_quote_format:
%A Address (Email)
%D Date (uses date_format)
%F Full address (%N <%A>)
%G Groupname
%M Message-ID
%N Fullname of author
%C Firstname of author
%I Initials of author
e.g.,
mail_quote_format=On %D in %G you wrote:
news_quote_format=In %M, %F wrote:
would expand to:
On 21 Sep 1993 09:45:51 -0400 in alt.sources you wrote:
In <abcINN123@example.org>, Joe Bar <joe@example.org> wrote:
The quoted text section of an article is marked by a preceding quote
string at the beginning of each quoted line. The default quote string
is set to '>_'. The default can be changed by setting the tinrc vari-
able quote_chars to ones own preference. (Note that '_' underline is
used to represent a space).

MAILING PIPING PRINTING REPOSTING AND SAVING ARTICLES
The command interface to GroupMail, PageMail, PostMail or ThreadMail
('m'), Pipe ('|'), Print ('o'), PageRepost or GroupRepost ('x') and
GroupSave, PageSave or ThreadSave ('s' and GroupAutoSave, PageAutoSave
or ThreadAutoSave 'S') articles is the same for ease of use.

Auto-saving with *AutoSave ('S') is a special case and operates only on
marked articles. They will processed without any further prompting ac-
cording to the default save parameters defined in tinrc or by any at-
tributes set for the current group.

Otherwise, the initial prompt will ask you to select which article,
thread, hot (auto-selected), regular expression pattern, tagged arti-
cles you wish to mail, pipe etc.

Tagged articles must have already been tagged with a *Tag ('t') com-
mand. All tagged articles can be untagged by a *Untag ('U') untag com-
mand.

If a regular expression pattern is selected you are asked to enter a
pattern (e.g., to match all articles subject lines containing 'net
News' you enter "net News"). Any articles that match the entered ex-
pression will be mailed, piped etc. See also the wildcard tinrc vari-
able for advanced pattern matching options.

Various expansion characters are recognized when entering the directory
and file to save to. Environment variables (prefixed with '$') and user
home directories (prefixed by '~' or '~username') can be specified.
Environment variables can themselves contain other special characters.

To save articles to a mailbox enter '=<mailbox name>' when asked for
the save filename. If you enter just '=' then articles will be saved to
a mailbox with the name of the current newsgroup (eg, alt.sources).
See maildir.

To save in savedir/<news.group.name>/<filename> format enter '+<file-
name>'. See savedir. Like '+' %G is expanded to the current
news.group.name but without savedir prefixed. %P is expanded to the
news.group.name with all '.' replaced by '/'.

If saving multiple files at once the filename (if not referring to a
mailbox) will be extended by ".num" where "num" is at least 3 digit
number counting up from 1. Environment variables are allowed within a
filename (e.g., $SOURCES/dir/filename).

When saving articles you can specify whether the saved files should be
post processed. A default process type can be set via
post_process_type.

AUTOMATIC MAILING AND SAVING NEW NEWS
tin allows new/unread news articles to be mailed (''-M'' and ''-N'' op-
tion) or saved (''-S'' option) in batch mode for later reading. Useful
when going on holiday and you don't want to return and find that expire
has removed a whole load of unread articles. Best to run via cron(8)
everyday while away, after which you will be mailed a report of which
articles were mailed/saved from which newsgroups and the total number
of articles mailed/saved. Articles are saved in a private news struc-
ture under your savedir directory (default is ${TIN_HOME-
DIR:-"$HOME"}/News). Be careful of using this option if you read a lot
of groups because you could overflow your file system.

When using ''-S'' together with a given directory to save to (''-s''
option), the same directory must be specified when reading the articles
by ''-R''.

If you only want to save some of your groups use the batch_save tinrc
variable. Set to ON or OFF in tinrc to enable/disable saving of all
groups and then use the batch_save attribute to fine tune which groups
you want to have saved. For example, if you want to save most of your
groups, then set batch_save to ON in tinrc and selectively turn off the
ones you don't want using attributes.

tin -M iain -c -f newsrc.mail
(mail any unread articles in newsgroups specified
in file newsrc.mail to the local user iain and mark
them as read)

tin -S -c -f newsrc.save
(save any unread articles in newsgroups specified
in file newsrc.save and mark them as read)

tin -R (read any articles saved by tin -S)

RANGES
A range is simply a group of items marked using the SetRange ('#') key.
Certain tin commands will operate on a range if one exists rather than
just the current item. A range is an expression of the form
<min>-<max>, e.g. 10-15 will highlight items 10 through 15 on the cur-
rent screen. Other than absolute numeric positions, '.' can be used in
place of the current cursor position and '$' can be used to mean the
highest number available. Entering '0' at the prompt undoes the previ-
ously entered range selection. Currently the only commands that under-
stand ranges are GroupMarkThdRead ('K'), MarkArtUnread ('z') and Mark-
ThdUnread ('Z').

NEWSGROUP LISTS & WILDCARDS
Several places in tin allow you to specify a list of newsgroups. These
include command-line groups, (un)subscribe groups, the AUTO[UN]SUB-
SCRIBE mechanism. The scope= attributes file tag and the filter file
group= tag also use the same syntax. tin interprets this variable simi-
larly to rn(1). It contains a list of patterns, separated by commas
and possibly prefixed with exclamation points. An exclamation point
negates the meaning of a match on this pattern, and can be used to can-
cel certain matches. See wildmat(3) for details about the understood
patterns. Some examples:

alt.config,news.*,!news.test

Matches alt.config and everything in the 'news' hierarchy except
news.test

See the explanation for the $AUTOSUBSCRIBE and $AUTOUNSUBSCRIBE vari-
ables for further examples.

SIGNATURES
tin will recognize a signature in either ${TIN_HOMEDIR:-"$HOME"}/.sig-
nature or ${TIN_HOMEDIR:-"$HOME"}/.Sig. If ${TIN_HOME-
DIR:-"$HOME"}/.signature exists, then the signature will be pulled into
the editor for mail commands only. A signature in ${TIN_HOME-
DIR:-"$HOME"}/.signature will not be pulled into the editor for posting
commands since inews(1) will append the signature itself.

A signature in ${TIN_HOMEDIR:-"$HOME"}/.Sig will be pulled into the ed-
itor for both posting and mailing commands.

The following is an example of a .Sig file:
NAMES Joe Bar <joe@example.org>
SNAIL Musterweg 12, 99999 Notreal, Germany

tin also has the capability to generate random signatures on a per
newsgroup basis if so desired. The way to accomplish this is to specify
the default signature or the group attribute sigfile as a directory. If
for example the sigfile path is /usr/iain/.sigs and .sigs is a direc-
tory then tin will select a random signature from any file that is in
the directory .sigs (note: one signature per numbered file). A random
signature can also consist of a fixed part signature that can contain
your name, address etc. followed by the random sig. The fixed part of
the random sig is read from the file $HOME/.sigfixed.

CUSTOMIZING THE SCREEN FORMAT
The look of the Selection, Group and Thread level can be customized via
format strings. These format strings define the content and the posi-
tion of each element on the screen. Variables are used within the for-
mat strings as placeholders. The following variables are available:

%D date
%F from, name and/or address
%G newsgroup name
%I initials
%L line count
%M message-id
%R number of responses in thread
%S score
%T thread tree
%U unread count
%d newsgroup description
%f newsgroup flag
%m article marks
%n current group/thread/article number
%s subject
%% %

Not all variables can be used in each level. The following table pro-
vides an overview:

select_format group_format thread_format
%D X X
%F X X
%G X
%I X X
%L X X
%M X X
%R X
%S X X
%T X
%U X
%d X
%f X
%m X X
%n X X X
%s X
%% X X X

Defaults for the format strings:

select_format: "%f %n %U %G %d"
group_format: "%n %m %R %L %s %F"
thread_format: "%n %m [%L] %T %F"

show_description controls whether the newsgroup description is shown or
not. The description can also be toggled with SelectToggleDescriptions
('d').

The information displayed with '%F' depends on the value of show_au-
thor. GroupToggleSubjDisplay resp. ThreadToggleSubjDisplay ('d')
switches through all available options.

For date representation '%D' uses date_format. It is possible to spec-
ify a different date format in round brackets (e.g. '%(%d %b %y
%H:%M)D'). See date_format for more details.

The length of each item (except '%%') can be defined with a positive
number after the '%'. The following example displays the score in the
thread level 10 characters wide: '%10S'.

If the newsgroup name is displayed together with the newsgroup descrip-
tion, the width of the newsgroup name can be controlled via an optional
comma separated second value (e.g. '%60,20G'). It is valid to omit the
first value (e.g. ('%,20G')). If no second value is given, tin uses a
default value of 32.

Some variables do have a default width which may lead to truncation.
Truncation for variables which contain only numbers happens by dividing
the value with a sufficient power of ten and adding a SI suffix to the
result, that is the variable holds a value of 54321 and the width for
the variable is 4 the result will be "54 k". If that's undesired you
have to specify a larger width manually, e.g. '%6n'. Here is an over-
view of the defaults:

Variable width
%I 3
%L 4
%M 10
%R 3
%S 6
%U 5
%n 4

If no length is given for '%D', the length is determined by the format
string for the date and the date of the current day. If the date format
string contains weekdays or months names it may happen that the date is
longer than determined in the first pass. In this case, the date is
truncated before display. This occurs, for example, if the current
month is May and the article to which the date is displayed was posted
in December. In such cases it might useful to determine the maximum
length manually and specify the length in the format string.

In case the format string contains '%G' and '%d' and no length are
given, tin determines the longest newsgroup name and uses this length
for '%G'. The remaining space will used for '%d'.

When the format string contains the specifier '%F' and '%s' resp. '%T'
and no length are given, '%F' will use one third and '%s' resp. '%T'
will use two third of the available space.

In addition, a minimum screen width can be defined for each item (ex-
cept '%%'). In this case, the item will only be displayed when the
screen is wider than specified. This comes in handy to not overload a
small screen but have maximum information on a large screen. The mini-
mum screen width has to be specified by a positive number preceded by
an '>'. In the following example tin will display the score only if the
screen is wider than 100 characters: '%>100S'.

If both the length and the minimum screen width should be specified for
an item, the length must be the first parameter and the minimum screen
width must be the second one. The following example displays the score
with a length of 10 characters only if the screen is wider than 100
characters: '%10>100S'.

The look of the Attachment level and the mime and uue header at Page
level can be customized too via format strings. The following vari-
ables are available:

%C Charset
%c Like %C but with description
%D Line count
%d Like %D but with description
%E Content encoding
%e Like %E but with description
%I Complete/incomplete UUE part indicator
%L Language
%l Like %L but with description
%N Name
%n Like %N but with description
%S Content subtype
%s Like %S but with description
%T Content type
%t Like %T but with description
%Z Size in bytes
%z Like %Z but with description
%% %

Not all items can be used in each variable. The following table pro-
vides an overview:

attachment_format page_mime_format page_uue_format
%C X X
%c X X
%D X X X
%d X X X
%E X X X
%e X X X
%I X
%L X X
%l X X
%N X X
%n X X
%S X X X
%s X X X
%T X X X
%t X X X
%Z X X X
%z X X X
%% X X X

By default, the string is not truncated. If it exceeds the screen
width, it is wrapped. If the % sign is followed by an exclamation mark
('!') for uppercase letters, the element is omitted if there is not
enough space. If the % sign is followed by an asterisk ('*') for a low-
ercase letter, the description is omitted if there is not enough space.
If the % sign is followed by an exclamation mark ('!') for a lowercase
letter, the description is omitted first and then the content. The
shortening is always from right to left, first the description is omit-
ted and when no more description is displayed, the content is omitted.
If %T and %S follow each other directly a '/' will be inserted in be-
tween. %Z will always have one decimal point and may have a one letter
bi-suffix.

Defaults for the format strings:

attachment_format: "%T%S%E%C%d"
page_mime_format: "[-- %T%S%*n%z%*l%!c%!d%*e --]"
page_uue_format: "[-- %T%S%*n%I%!d%*e --]"

TIPS AND TRICKS
tin can be pretty much be navigated by using the four cursor keys. The
left arrow key goes up a level, the right arrow key goes down a level,
the up arrow key goes up a line and the down arrow key goes down a
line.

The following newsgroups provide useful information concerning news
software:
--news.software.readers (info. about news user agents tin, rn, nn,
slrn etc.)
--news.software.nntp (info. about NNTP)
--news.answers (Frequently Asked Questions (FAQ) about many differ-
ent themes)

Many prompts within tin offer a default choice that the cursor is posi-
tioned on. By pressing '<CR>' the default value is taken. Most prompts
can be aborted by pressing '<ESC>'.

When tin is run in an xterm(1x) it will resize itself each time the
xterm(1x) is resized.

tin will reread the ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-ac-
tive} file at set intervals (reread_active_file_secs) to show any newly
arrived news.

If you find large number of new newsgroups cluttering up your screen,
pressing SelectToggleReadDisplay ('r') will make them go away.

XTERM BUTTONS
If the environment variable $TERM is set to xterm(1x), then button
pressing can be used to select groups and articles. In this discussion,
the buttons are assumed to be assigned conventionally (i.e., Button1 is
the left button).

In general (i.e., for the group, thread and article menus),

Button1 (left)
enters next (lower) level if you click on an article, other-
wise pages down.

Button2 (center)
returns to the previous (upper) level if you click on an ar-
ticle, otherwise pages up.

Button3 (right)
positions on the article line under mouse cursor, or pages
down if you've clicked outside the list of articles.

In the group selection menu, if the mouse is pointing at a group then:

left button
moves to and selects the group pointed at, just like Selec-
tReadGrp ('<CR>').

center button
quits the program, just like Quit ('q').

right button
moves to the group pointed at.

In the article menu, if the mouse is pointing at an article (or thread)
then:

left button
reads the article pointed at, just like GroupReadBasenote
('<CR>'), or the thread, just like GroupListThd ('l').

center button
exits the menu, catching up on the group if you have
group_catchup_on_exit set in your configuration, just like
Quit ('q').

right button
moves to the article (or thread) pointed at.

In the thread menu, if the mouse is pointing at an article then:

left button
reads article pointed at, just like ThreadReadArt ('<CR>').

center button
exits the menu, catching up on the thread if you have
thread_catchup_on_exit set in your configuration, just like
Quit ('q').

right button
moves to the article pointed at.

In other menus and areas button pressing reverts back to usual cut and
paste of xterm(1x), but after one click of any button.

INDEX FILES
If your news server supports NOV index files (see newsoverview(5), most
modern installations will) and you have a fast connection to your news
server then this section can be ignored.

If your news server doesn't support NOV index files or you have a very
slow connection to your news server then tin can cache the index for
each newsgroup if cache_overview_files is set to ON. Note that this
cache can use up large amounts of disk space if you read a lot of
groups and/or high traffic groups.

Each user creates/updates his/her own index files that are stored in
${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news/. If you are
reading via NNTP then the news server name will be appended to keep the
indexes for different servers separate. If you are reading off the lo-
cal spool and local overview files already exist then turning on
caching will have no effect. Likewise unless you see significant delays
entering a group when reading via NNTP then turning on caching will
have little or no effect.

Entering a group the first time tends to be slow because the index file
must be built from scratch. To alleviate the slowness start tin to cre-
ate all index files for the groups you subscribe to with tin -u -v and
go for a coffee. Subsequent readings of a group will only need to do
incremental updating of the index file and will be much faster as only
new articles will need to be cached.

As indexing might take some time you may want to run tin from the sys-
tem batcher cron(8) with the ''-u'' option:

30 6 * * * /usr/local/bin/tin -u

If you are low on local disk space you should consider to manually
purge cached data for groups you are not reading anymore with something
like:

find ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news* \
-type f -name "[0-9]*.[0-9]" -atime +28 | xargs rm -f

ENVIRONMENT
TINRC Define this variable if you want to specify command-line options
that tin should be started with to save typing them each time it
is started. The contents of the environment variable are added
to the front of the command-line options before it is parsed
therefore allowing an option specified on the command-line to
override the same option specified in the environment.

TIN_HOMEDIR
Define this variable if you do not want the .tin directory in
$HOME/. E.g., if you want all tin's private files in /tmp/.tin
you would set $TIN_HOMEDIR to /tmp.

TIN_INDEX_NEWSDIR
Define this variable if you do not want the .news directory in
${TIN_HOMEDIR:-"$HOME"}/.tin/. E.g., if you want all tin's news
index files in /tmp/.news you would set $TIN_INDEX_NEWSDIR to
/tmp.

TIN_INDEX_MAILDIR
Define this variable if you do not want the .mail directory in
${TIN_HOMEDIR:-"$HOME"}/.tin/. E.g., if you want all tin's mail
index files in /tmp/.mail you would set $TIN_INDEX_MAILDIR to
/tmp.

TIN_INDEX_SAVEDIR
Define this variable if you do not want the .save directory in
${TIN_HOMEDIR:-"$HOME"}/.tin/. E.g., if you want all tin's save
index files in /tmp/.save you would set $TIN_INDEX_SAVEDIR to
/tmp.

TIN_LIBDIR
Define this variable if you want to override the NEWSLIBDIR path
that was compiled into the tin binary, default is /usr/lib/news.
If tin is running in NNTP mode setting this variable has no ef-
fect.

TIN_SPOOLDIR
Define this variable if you want to override the SPOOLDIR path
that was compiled into the tin binary, default is
/var/spool/news. If tin is running in NNTP mode setting this
variable has no effect.

TIN_NOVROOTDIR
Define this variable if you want to override the NOVROOTDIR path
that was compiled into the tin binary, default is SPOOLDIR (see
above). If tin is running in NNTP mode setting this variable has
no effect.

TIN_NOVFILENAME
Define this variable if you want to override the OVERVIEW_FILE
filename that was compiled into the tin binary, default is
.overview. If tin is running in NNTP mode setting this variable
has no effect.

TIN_ACTIVEFILE
Define this variable if you want to override the NEWSLIBDIR/ac-
tive path that was compiled into the tin binary. If tin is run-
ning in NNTP mode setting this variable has no effect. If
$TIN_LIBDIR is set it is prepended to $TIN_ACTIVEFILE.

NNTPSERVER
The default NNTP server to remotely read news from. This vari-
able only needs to be set if the ''-r'' command-line option is
specified and the file /etc/nntpserver does not exist. The
''-g'' command line option overrides $NNTPSERVER.

NNTPPORT
The NNTP TCP-port to read news from. This variable only needs to
be set if the TCP-port is not 119 (the default). The ''-p'' and
''-T'' command-line options do override $NNTPPORT.

DISTRIBUTION
Set the article header field ''Distribution:'' to the contents
of the variable instead of the system default.

ISO2ASC
Set the ISO to ASCII charset decoding table character to use in
decoding an article text. Values can range from -1 to 6.

-1 no conversion

0 universal table for many languages

1 single-spacing universal table

2 table for Danish, Dutch, German, Norwegian and Swedish

3 table for Danish, Finnish, Norwegian and Swedish using the
appropriate ISO 646 variant

4 table with RFC1345 codes in brackets

5 table for printers that allow overstriking with backspace

6 table for IBM PC character set (code page 437)

ORGANIZATION
Set the article header field ''Organization:'' to the contents
of the variable instead of the system default. If it points to a
readable file a random line from that file will be used. If
reading news on an Apollo DomainOS machine the environment vari-
able $NEWSORG has to be used instead of $ORGANIZATION.

NEWSORG (DomainOS)
DomainOS specific, same as $ORGANIZATION on other OSs (see
above).

REPLYTO
Set the article header field ''Reply-To:'' to the return address
specified by the variable. This is useful if you wish to receive
replies at a different address.

NAME Overrides the full name given in the gecos-field in /etc/passwd,
see also mail_address.

REALNAME
Same as $NAME.

HOME Pathname of the user's home directory. See environ(5) for more
info.

MAILER This variable has precedence over the default mailer that is
used in all mailing operations within tin.

MAIL Full path to the user's mailbox.

VISUAL This variable has precedence over the default editor (i.e.,
vi(1)) that is used in all editing operations within tin (e.g.,
posting, replying, follow-ups, ...). Evaluation order is ${VIS-
UAL:-"${EDITOR:-vi}"}. See environ(5) for more info.

EDITOR If $VISUAL is unset, then this variable is looked up for a de-
fault editor. If $EDITOR and $VISUAL are both unset, tin uses
the systems default editor (i.e. vi(1) on UNIX-systems). See
environ(5) for more info.

AUTOSUBSCRIBE
A new group is checked against the list of patterns; if it
matches, tin subscribes the user to the group without further
query. See the section "NEWSGROUP LISTS & WILDCARDS" for an ex-
planation of the valid syntax. For example, setting

AUTOSUBSCRIBE=comp.os.unix.*,talk.*,!talk.politics.*

will automatically subscribe the user to all new groups in the
comp.os.unix hierarchy, and all talk groups other than talk.pol-
itics groups (which will be queried for as usual). Of course
this does not work if tin is started with the ''-X'' command-
line switch.

AUTOUNSUBSCRIBE
Is handled like the $AUTOSUBSCRIBE variable, but groups matching
the list are unsubscribed from without further query. For exam-
ple, setting

AUTOUNSUBSCRIBE=alt.flame.*,u*,!uk.*

will automatically unsubscribe the user from all new alt.flame
groups and all groups starting with u (university groups) other
than UK groups (which will be queried for as usual).

TMPDIR A pathname of a directory made available for tin to create tem-
porary files.

MAILCAPS
This variable can be used to override the default path search
for mailcap(5) files. See also tin(5).

NOMETAMAIL
Set this variable to disable the use of metamail(1) or a re-
placement (e.g. metamutt).

MM_CHARSET
MIME character set used if not configured via the tinrc variable
mm_charset.

ISPELL Set this variable to point to ispell(1) or a replacement and its
cmd-line options.

PGPOPTS
Define any additional options that you wish to pass to your
pgp(1) or gpg(1) program.

PGPPATH
Override the name of the pgp(1) directory in $HOME that holds
your keys etc..

GNUPGHOME
Override the name of the gpg(1) directory in $HOME that holds
your keys etc..

LC_CTYPE
This variable determines the locale(5) category for character
handling functions. Usually it determines the character classes
for pattern matching character classification and case conver-
sion. Currently this is not true for tin (which temporary unsets
$LC_CTYPE right before any match is done to avoid confusion).
Its value should be of the form language[_territory][.code-
set][@modifier]. See environ(5) for more information.

LC_MESSAGES
Formats of informative and diagnostic messages and interactive
responses. Its value should be of the form language[_terri-
tory][.codeset][@modifier]. See locale(5) and environ(5) for
more information.

LC_TIME
Date and time formats. Its value should be of the form lan-
guage[_territory][.codeset][@modifier]. See locale(5) and
environ(5) for more information.

LC_ALL This variable overrides the value of the $LANG variable and any
other $LC_ variable. Its value should be of the form lan-
guage[_territory][.codeset]. See locale(5) and environ(5) for
more information.

LANG This variable determines the locale(5) category for any category
not specifically selected with a variable starting with $LC_.
Its value should be of the form language[_territory][.codeset].
See environ(5) for more information.

LANGUAGE
This variable defines a priority list for translations. Whenever
a translation is not available in the language selected via
$LC_ALL or $LANG the next language from the list is tried. Its
value should be of the form language:language[:language]. See
environ(5) for more information.

COLUMNS
A decimal integer > 0 used to indicate the user's preferred
width in column positions for the terminal screen or window. If
this variable is unset or null, the implementation determines
the number of columns, appropriate for the terminal or window.
When $COLUMNS is set, any terminal-width information implied by
$TERM will be overridden. Users and portable applications should
not set $COLUMNS unless they wish to override the system selec-
tion and produce output unrelated to the terminal characteris-
tics.

LINES A decimal integer > 0 used to indicate the user's preferred num-
ber of lines on a page or the vertical screen or window size in
lines. A line in this case is a vertical measure large enough to
hold the tallest character in the character set being displayed.
If this variable is unset or null, the implementation determines
the number of lines, appropriate for the terminal or window.
When $LINES is set, any terminal-height information implied by
$TERM will be overridden. Users and portable applications should
not set $LINES unless they wish to override the system selec-
tion.

TERM The type of terminal in use. This is used when looking up term-
cap sequences. See environ(5) for more information.

DISPLAY
Display name, pointing to the X server; required for xface.

WINDOWID
Used for determining terminal's X window id; required for xface.
Should be set by the terminal emulator.

SHELL The pathname of the user's login shell. Used to set de-
fault_shell_command.

XDG_RUNTIME_DIR
The pathname of the user's dir to put non-essential run time
files into.

SIGNALS
tin handles a couple of signals:

SIGHUP Terminate gracefully.

SIGTERM
Terminate gracefully.

SIGUSR1
Terminate gracefully but do not restore terminal (tty).

SIGUSR2
Write out ${TIN_HOMEDIR:-"$HOME"}/.newsrc-file.

SECURITY
If tin is started in debug mode (''-D n'') it will create world read-
able files in $TMPDIR which may contain sensitive data like the users
NNTP password in cleartext (if running verbose). On multiuser-systems
$TMPDIR should be set to a safe location before starting tin in (ver-
bose) debug mode (e.g. TMPDIR=$HOME tin -vD 1).

Using the ''-k'' option to skip certificate verification makes the ses-
sion insecure as the server's certificate is not checked; avoid this
option whenever possible.

If the server does not initially require authentication but supports
compression and compression is requested, tin will exit when authenti-
cation is required later on. Using the ''-A'' command line option in
conjunction with ''-C'' circumvents this behavior.

CONFORMING TO
tin does conform to the Base Definitions volume of IEEE Std
1003.1-2008, Section 12, Utility Conventions (Utility Argument Syntax,
Utility Syntax Guidelines).

NOTES
Regular expression support is provided by the PCRE library package
pcre(3) or pcre2(3) which is open source software, written by Philip
Hazel, and copyright (C) by the University of Cambridge, England.

BUGS
CNews NNTPd, noffle(1) (<= V1.0-pre5) and NewsCache (<= V1.1.91) can't
handle pipelined GROUP commands (RFC3977). If you run into trouble
with any of the mentioned historical servers define DISABLE_PIPELINING
in include/autoconf.h and recompile.

Using the ''-C'' (COMPRESS) flag with INN nnrpd versions between 2.6.1
and 2.7.1 (both incl.) may cause tin to hang and later timeout when
posting. This has been fixed in INN nnrpd version 2.7.2. As a work-
around simply don't use ''-C''.

Before mailing a bug-report to <tin-bugs@tin.org> please check if you

first! Have a look at the doc/TODO file for known bugs. If you still
think you've found a bug, please use the BugReport ('R') function and
write in English. Please do NOT enclose a core-file in your bug-report
until we request it.

HISTORY
tin is based on the tass(1) newsreader that was developed by Rich
Skrenta and posted to alt.sources in March 1991; its first version was
released on August 23rd 1991. tass(1) itself was heavily influenced by
notesfiles a public domain UNIX version of PLATO Notes, developed at
the University of Illinois by Ray Essick and Rob Kolstad in 1982. For a
version overview see
<http://www.tin.org/history.html>.
