NAME
ncftpput - Internet file transfer program for scripts
SYNOPSIS
ncftpput [options] remote-host remote-directory local-
files...
ncftpput -f login.cfg [options] remote-directory local-
files...
ncftpput -c remote-host remote-path-name < stdin
OPTIONS
Command line flags:
-u X Use username X instead of anonymous.
-p X Use password X with the username.
-P X Use port number X instead of the default FTP ser-
vice port (21).
-j X Use account X in supplement to the username and
password (deprecated).
-d X Use the file X for debug logging.
-a Use ASCI transfer type instead of binary.
-m Attempt to make the remote destination directory
before copying.
-t X Timeout after X seconds.
-U X Use value X for the umask.
-v/-V Do (do not) use progress meters. The default is to
use progress meters if the output stream is a TY.
-f X Read the file X for host, user, and password infor-
mation.
-A Append to remote files, instead of overwriting them.
-T X Upload into temporary files prefixed by X.
-S X Upload into temporary files suffixed by X.
-R Recursive mode; copy whole directory trees.
-r X Redial a maximum of X times until connected to the

remote FTP server.
-z/-Z Do (do not) try to resume transfers. The default is
to not 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.
-D Delete local file after successfully uploading it.
-y Try using "SITE UTIME" to preserve timestamps on
remote host. Not many remote FTP servers support
this, so it may not work.
-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 process-
ing 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 simul-
taneous FTP sessions to the same server.
-B X Try setting the TCP/IP socket buffer size to X
bytes.
-W X Send raw FTP command X after logging in.
-X X Send raw FTP command X after each file transferred.
-Y X Send raw FTP command X 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.

DESCRIPTION
The purpose of ncftpput 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 send files from the shell command line without
entering an interactive FTP program such as ncftp.
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 mypassword
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.
Using ASCI mode is helpful when the text format of your
host differs from that of the remote host. For example, if
you are sending a text file from a UNIX system to a
Windows-based host, you could use the -a flag which would
use ASCI transfer mode so that the file created on the Win-
dows machine would be in its native text format instead of
the UNIX text format.

You can upload an entire directory tree of files by using
the -R flag. Example:
$ ncftpput -R pikachu.nintendo.co.jp /incoming
/tmp/stuff
This would create a /incoming/stuff hierarchy on the remote
host.
The -T and -S options are useful when you want to upload
file to the remote host, but you don't want to use the des-
tination pathname until the file is complete. Using these
options, you will not destroy a remote file by the same name
until your file is finished. These options are also useful
when a remote process on the remote host polls a specific
filename, and you don't want that process to see that file
until you know the file is finished sending. Here is an
example that uploads to the file /pub/incoming/README, using
the filename /pub/incoming/README.tmp as a temporary
filename:
$ ncftpput -S .tmp bowser.nintendo.co.jp /pub/incoming
/a/README
A neat way to pipe the output from any local command into a
remote file is to use the -c option, which denotes that
you're using stdin as input. The following example shows
how to make a backup and store it on a remote machine:
$ tar cf - / ncftpput -c sonic.sega.co.jp
/usr/local/backup.tar
DIAGNOSTICS
