    NAME
         ncftpget - Internet file transfer program for scripts
    
    SYNOPSIS
         ncftpget  [options]  remote-host   local-directory   remote-
         files...
    
         ncftpget  -f  login.cfg  [options]  local-directory  remote-
         files...
    
         ncftpget [options] ftp://url.style/host/path/name
    
    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  ser-
                 vice port (21).
    
         -j XX   Use account XX in supplement  to  the  username  and
                 password (deprecated).
    
         -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 infor-
                 mation.
    
         -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  down-
                 loading  whole  directory  trees.  ncftpget uses TAR
                 whenever possible since this usually preserves  sym-
                 bolic links and file permissions.  TAR mode can also
                 result in faster transfers for directories  contain-
                 ing 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 portion 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   job   to
                 ncftpbatch).
    
         -B XX   Try setting the TCP/IP  socket  buffer  size  to  XX
                 bytes.
    
    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 useful for advanced users who
         want to retrieve files from the shell command  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  anonymously, but you can specify a username and pass-
         word 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.
