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

       ncftpget -c [options] remote-host remote-file > stdout

       ncftpget -c [options] ftp://url.style.host/path/name > stdout

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      Send output to standard out, rather than	 writing  to  a	 local
	       file.

       -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.

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.
