NAME
tin, rtin - A Usenet newsreader

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
a NNTP (Network News Transport Protocol) 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
Interactive mode:

0 Successful program execution.

1 Usage, syntax, configuration file or network error.

Batch mode (''-Z''):

0 No unread news

1 Usage, syntax, configuration file or network error.

2 Unread news

OPTIONS
-4 Force connecting via IPv4 to the remote NNTP server.

-6 Force connecting via IPv6 to the remote NNTP server.

-a Toggle ANSI color (default is off).

-A Force authentication on initial connect.

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

-d Don't load newsgroup descriptions (interactive mode).

-D debug-level
Enter debug-level (1 = NNTP, 2 = filter, 4 = newsrc, 8 =
threading, 16 = memory, 32 = attributes, 64 = misc).

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

-g server Use the server and newsrc specified in ${TIN_HOME-
DIR:-"$HOME"}/.tin/newsrctable.

-G article-limit
Limit the number of articles/group to retrieve from the
server.

-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_overview_files is turned off.

-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''.

-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
allows a noticeable speedup when connecting via a slow
line, but tin can not tell 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). This also
overrides the environment variable $NNTPPORT if set.

-q Don't check for new newsgroups.

-Q Quick start. Start tin as quickly as possible. Currently
this is equivalent to ''-nqd''.

-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''
option. For more information read section "AUTOMATIC MAIL-
ING AND SAVING NEW NEWS".

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

-v Verbose mode for ''-c'', ''-M'', ''-N'', ''-S'', ''-u'' and
''-Z'' options.

-V Print version and date information.

-w Quick mode to post an article and then exit. 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_ACTIVE-
FILE:-active} 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
options. Thus, command-line option takes precedence over configured
values.

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
directory (i.e., ${TIN_LIBDIR:-NEWSLIBDIR}/subscriptions) and should
have file permissions set to 0644. If you read news via NNTP, then your
news server must support the LIST SUBSCRIPTIONS command. It is part of
the NNTP List Extensions (RFC6048) and all modern servers should under-
stand 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 newsserver
and) the number of subscribed groups (containing new unread articles).
The newsgroups are displayed in the middle of the screen with the num-
ber of unread articles displayed on the same line in front.

->M 1 2 comp.security.announce Announcements from the CERT abou

3 22 news.software.misc News-related software other than
4 1475 news.software.nntp The Network News Transfer Protoc
X 5 124 news.software.readers Discussion of software used to r

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
newsserver 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 threading method, the limit of articles to
get, the total number of articles, the number of hot articles, the num-
ber of recent articles and the number of killed articles. 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 in it it's marked with a
art_marked_unread in front of the total number of articles in the
thread. If there are recent articles within the thread it might be
marked with art_marked_recent 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 number of lines of the first (unread) arti-
cle in the thread might also be shown right before the subject - this
is controlled by the show_info option.

COMMON EDITING COMMANDS
An emacs style editing package allows the easy editing of input
strings. An 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.

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, ${TIN_LIB-
DIR:-NEWSLIBDIR}/tinrc is read. After that, the user's own configura-
tion file is read from ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc. The global
file is useful for distributing 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.

attachment). If set to 'Hide all' then any line that looks like

lead to false positives. This setting can also be toggled in the
article viewer. Default is 'No'.

headers (old use_mailreader_i=ON option). 0 turns off usage. This
option has to suit mailer_format. Default is 0.

Default is ON.

Keep failed arts in ~/dead.articles (keep_dead_articles)
If ON keep all failed postings in ${TIN_HOME-

Filter which articles (kill_level)

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.

ing is also set to 8bit. Leaving it OFF is safe for most users and
compliant to Internet Mail Standard (RFC5322 and RFC2047). Default
is OFF.

used when creating articles, sending mail and when pgp(1) signing.

MIME encoding in mail messages (mail_mime_encoding)

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=Address, %D=Date, %F=Fullname+Address, %G=Groupname, %M=Mes-
sage-ID, %N=Fullname, %C=Firstname, %I=Initials). Default is "In

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 elm(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 format
allows other mailers with different command-line parameters to be
used such as 'elm -s "%S" "%T" < "%F"' (e.g., elm -s "subject"
"iain" < .article) or 'sendmail -oi -oem -t < %F' (e.g. sendmail
-oi -oem -t < .article).

'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
installed. Leave it blank if you don't want any automatic viewing
of non-textual attachments. The 'V' command can always 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_display_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
anything turns off this option.

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

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_encoding is also set to 8bit. In a number of local hier-
archies 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 hier-
archy 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.

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)

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
from the ${TIN_LIBDIR:-NEWSLIBDIR}/newsgroups file and if supported
(requires tin to be build with mh-mail-handling support) from
${TIN_HOMEDIR:-"$HOME"}/.tin/mailgroups for mailgroups. Default is

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. tin will pass the name of the current newsgroup as argument
to the program. --none will suppress any signature. Default is
${TIN_HOMEDIR:-"$HOME"}/.Sig.

Add signature when reposting (signature_repost)
If ON add signature to reposted articles. Default is ON.

Regex used to highlight /slashes/ (slashes_regex)

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 notation, which is how this has traditionally been
handled. Setting this to 1 allows you to use perl(1) compatible
regular expressions pcre(3) (see also perlre(1) and pcrepat-
tern(3)). You will probably want to update your filter file if you
use this regularly. NB: Newsgroup names will always be matched
using the wildmat 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)

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
option 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 cross-posting (xpost_quote_format)
Format is the same as for news_quote_format, this is used when
answering 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
exists, the global attributes file, ${TIN_LIBDIR:-NEWSLIB-
DIR}/attributes is read. After that, the user's own attributes file
${TIN_HOMEDIR:-"$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
attributes are specified for that list. All attributes are set to a
reasonable default so you only have to specify the attribute that you
want to change (e.g., savedir). All toggle attributes are set by speci-
fying 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.

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 '^K' 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:'' lines of an article. The kill description 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 kill
description, edit the kill file or save the kill description.

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.

Use the PageFollowupQuote ('f'), PageFollowup ('F') or PageFol-
lowupQuoteHeaders ('^W') command to post a follow-up article to an
already posted article. The PageFollowupQuote command will copy the
text of the original article into the editor. The PageFollowupQuote-
Headers 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 article 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
editor. 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
beginning of the quoted text can contain information about the quoted
article (e.g., Name and the Message-ID of the article). To allow for
different 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:

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
according to the default save parameters defined in tinrc or by any
attributes set for the current group.

Otherwise, the initial prompt will ask you to select which article,
thread, hot (auto-selected), regex pattern, tagged articles 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 regex 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 expression will be
mailed, piped etc. See also the wildcard tinrc variable 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>'. Environment variables are allowed within a filename (e.g.,
$SOURCES/dir/filename). See savedir.

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

AUTOMATIC MAILING AND SAVING NEW NEWS
tin allows new/unread news articles to be mailed (''-M'' and ''-N''
option) or saved (''-S'' option) in batch mode for later reading. Use-
ful 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(1) 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
structure 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. Currently the only commands that understand
ranges are GroupMarkThdRead ('K'), MarkArtUnread ('z') and MarkThdUn-
read ('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. 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 variables for further exam-
ples.

SIGNATURES
tin will recognize a signature in either ${TIN_HOMEDIR:-"$HOME"}/.sig-
nature or ${TIN_HOMEDIR:-"$HOME"}/.Sig. If
${TIN_HOMEDIR:-"$HOME"}/.signature exists, then the signature will be
pulled into the editor for mail commands only. A signature in
${TIN_HOMEDIR:-"$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
editor 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.

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_ACTIVE-
FILE:-active} 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
article, 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 diskspace 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
local 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 form the sys-
tem batcher cron(1) with the ''-u'' option:

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

If you are low on local disk space you should consider using
getart_limit to limit the size of cached indexes and also 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
effect.

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_ACTIVEFILE
Define this variable if you want to override the NEWSLIB-
DIR/active path that was compiled into the tin binary. If tin is
running 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''
command-line option overrides $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 0 to 6.

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 RFC 1345 codes in brackets

5 table for printers that allow overstriking with backspace

ORGANIZATION
Set the article header field ''Organization:'' to the contents
of the variable instead of the system default. If reading news
on an Apollo DomainOS machine the environment variable $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-files 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
${VISUAL:-"${EDITOR:-vi}"}. See environ(5) for more info.

EDITOR If $VISUAL is unset, then this variable is looked up for a
default 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
explanation 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 files. See also tin(5).

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

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).
It's 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. It's 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. It's value should be of the form lan-
guage[_territory][.codeset][@modifier]. See locale(5) and envi-
ron(5) for more information.

LC_ALL This variable overrides the value of the $LANG variable and any
other $LC_ variable. It's 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_.
It's 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. It's
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.

SIGNALS
tin handles a couple of signals:

SIGHUP Terminate gracefully.

SIGTERM
Terminate gracefully.

SIGUSR1
Terminate gracefully but do not restore tty.

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

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

CONFORMING TO
tin does conform to the Base Definitions volume of IEEE Std
1003.1-2001, Section 12, Utility Conventions (Utility Argument Syntax,
Utility Syntax Guidelines).

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>.
