NAME

ncftpput - Internet file transfer program for scripts

SYNOPSIS

ncftpput [options] remote-host remote-directory local-files...

ncftpput [options] bookmark-name remote-directory local-files...

ncftpput -f login.cfg [options] remote-directory local-files...

ncftpput -c remote-host remote-path-name < stdin

ncftpput -C remote-host local-path-name remote-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 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.

-m Attempt to make the remote destination directory before copying.

-t XX Timeout after XX seconds.

-U XX Use value XX for the umask.

-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 locally from standard input and write remotely to specified pathname.

-C Similar to -c, except a local pathname is specified.

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

-T XX Upload into temporary files prefixed by XX.

-S XX Upload into temporary files suffixed by XX.

-R Recursive mode; copy whole directory trees.

-r XX Redial a maximum of XX 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.

-DD 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 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,
STATfileParamWorks, NLSTfileParamWorks, require20, allowProxyForPORT,
doNotGetStartCWD.

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 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 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 ASCII 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 ASCII transfer mode so that the file
created on the Windows 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 destination 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

ncftpput returns the following exit values:

0 Success.

4 Transfer failed - timed out.

5 Directory change failed.

6 Directory change failed - timed out.

7 Malformed URL.

8 Usage error.

9 Error in login configuration file.
