OPTIONS
   Command line flags:
       -u XX   Use username XX instead of anonymous.

       -p XX   Use password XX with the username.

       -P XX   Use  port  number  XX  instead  of the default FTP service port
               (21).

       -j XX   Use account XX in supplement to the username and password (dep-
               recated).

       -d XX   Use the file XX for debug logging.

       -a      Use ASCII transfer type instead of binary.

       -t XX   Timeout after XX seconds.

       -v/-V   Do  (do  not)  use  progress  meters.   The  default  is to use
               progress meters if the output stream is a TTY.

       -f XX   Read the file XX for host, user, and password information.

       -c      Read from remote host and write locally to standard out.

       -C      Read from remote host and write locally to specified pathname.

       -A      Append to local files, instead of overwriting them.

       -z/-Z   Do (do not) try to resume transfers.  The default is to try  to
               resume (-z).

       -E      Use regular (PORT) data connections.

       -F      Use  passive  (PASV)  data  connections.  The default is to use
               passive, but to fallback to regular if the  passive  connection
               fails or times out.

       -DD     Delete remote file after successfully downloading it.

       -R      Recursive mode; copy whole directory trees.

       -T      Do  not use automatic on-the-fly TAR mode for downloading whole
               directory trees.  ncftpget uses  TAR  whenever  possible  since
               this  usually  preserves  symbolic  links and file permissions.
               TAR mode can also result in faster  transfers  for  directories
               containing many small files, since a single data connection can
               be used rather than an FTP data connection for each small file.
               The  downside to using TAR is that it forces downloading of the
               whole directory, even if you had previously downloaded  a  por-
               tion  of  it earlier, so you may want to use this option if you
               want to resume downloading of a directory.

       -r XX   Redial a maximum of XX times until connected to the remote  FTP
               server.

       -b      Run  in background (by submitting a batch job and then spawning
               ncftpbatch).

       -bb     Similar to -b option, but only submits the batch job.  You will
               need to run ncftpbatch for the batch job to be processed.  This
               is useful if you already have a ncftpbatch process running,  or
               wish to have better control of when batch jobs are processed.

               For example, if you wanted to do background processing of three
               files all on the same remote server, it is more polite  to  use
               just  one  ncftpbatch process to process the three jobs sequen-
               tially, rather than  having  three  ncftpbatch  processes  open
               three simultaneous FTP sessions to the same server.

       -B XX   Try setting the TCP/IP socket buffer size to XX bytes.

       -W XX   Send raw FTP command XX after logging in.

       -X XX   Send raw FTP command XX after each file transferred.

       -Y XX   Send raw FTP command XX before logging out.

               The  -W,  -X,  and -Y options are useful for advanced users who
               need to tweak behavior on some  servers.   For  example,  users
               accessing  mainframes might need to send some special SITE com-
               mands to set blocksize and record format information.

               For these options, you can use them multiple times each if  you
               need to send multiple commands.  For the -X option, you can use
               the cookie %s to expand into the name  of  the  file  that  was
               transferred.

       -o XX   Set advanced option XX.

               This option is used primarily for debugging.  It sets the value
               of an internal variable to an integer value.  An example  usage
               would  be:  -o useFEAT=0,useCLNT=1 which in this case, disables
               use of the FEAT command and  enables  the  CLNT  command.   The
               available  variables  include: usePASV, useSIZE, useMDTM, useR-
               EST, useNLST_a, useNLST_d, useFEAT, useMLSD, useMLST,  useCLNT,
               useHELP_SITE, useSITE_UTIME, STATfileParamWorks, NLSTfileParam-
               Works, require20, allowProxyForPORT, doNotGetStartCWD.

DESCRIPTION
       The purpose of ncftpget is to do file transfers from  the  command-line
       without  entering  an  interactive  shell.   This  lets you write shell
       scripts or other unattended processes that can do FTP.  It is also use-
       ful  for  advanced users who want to retrieve files from the shell com-
       mand line without entering an interactive FTP program such as ncftp.

       One particularly useful feature of this program is that you can give it
       a  uniform  resource  locator as the only argument and the program will
       download that file.  You can then copy and paste from your web  browser
       or newsreader and use that URL.  Example:

           $ cd /tmp
           $ ncftpget ftp://ftp.ncftp.com/pub/ncftp/ncftp.tar.Z
           $ zcat ncftp.tar.Z | tar xf -

       By  default  the program tries to open the remote host and login anony-
       mously, but you can specify a username and password  information.   The
       -u  option  is  used  to  specify  the username to login as, and the -p
       option is used to specify the password.  If you are running the program
       from  the shell, you may omit the -p option and the program will prompt
       you for the password.

       Using the -u and -p options are not recommended, because  your  account
       information  is exposed to anyone who can see your shell script or your
       process information.  For example, someone using the ps  program  could
       see your password while the program runs.

       You  may  use  the -f option instead to specify a file with the account
       information.  However, this is still not secure because anyone who  has
       read  access  to  the information file can see the account information.
       Nevertheless, if you choose to use the -f option the file  should  look
       something like this:

           host sphygmomanometer.ncftp.com
           user gleason
           pass mypasswd

       Don't  forget to change the permissions on this file so no one else can
       read them.

       The -d option is very useful when you are trying to diagnose why a file
       transfer  is failing.  It prints out the entire FTP conversation to the
       file you specify, so you can get an idea of what went  wrong.   If  you
       specify  the  special  name  stdout as the name of the debugging output
       file, the output will instead print to the screen.  Example:

           $ ncftpget -d stdout bowser.nintendo.co.jp . /pub/README
           220: FTP server ready.
           Connected to bowser.nintendo.co.jp.
           Cmd: USER anonymous
           331: Guest login ok, send your complete e-mail address as password.
           Cmd: PASS xxxxxxxx
           230: Welcome!
           Logged in to bowser.nintendo.co.jp as anonymous.
           Cmd: TYPE I
           200: Type set to I.
           Cmd: PORT 192,168,9,37,6,76
           200: PORT command successful.
           Cmd: RETR /pub/README
           550: /pub/README: File in use.
           Cmd: QUIT
           221: Goodbye.

       Using ASCII mode is helpful when the text format of your  host  differs
       from  that  of  the  remote host.  For example, if you are retrieving a
       .TXT file from a Windows-based host to a UNIX system, you could use the
       -a flag which would use ASCII transfer mode so that the file created on
       the UNIX system would be in the UNIX text format instead of the  MS-DOS
       text format.

       You  can  retrieve  an  entire  directory tree of files by using the -R
       flag.  However, this will work only if the remote FTP server is a  UNIX
       server, or emulates UNIX's list output.  Example:

           $ ncftpget -R ftp.ncftp.com /tmp /pub/ncftp

       This would create a /tmp/ncftp hierarchy.
