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 (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 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 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 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 sequentially, 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 commands 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,
               useREST, useNLST_a, useNLST_d, useFEAT, useMLSD, useMLST, useCLNT, useHELP_SITE,  useSITE_UTIME,  STAT-
               fileParamWorks, NLSTfileParamWorks, 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  useful  for
       advanced  users who want to retrieve files from the shell command line without entering an interactive FTP pro-
       gram 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 news-
       reader 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
       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  pro-
       gram 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.   Neverthe-
       less, 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  exam-
       ple,  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  for-
       mat 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.
