I need to do a lot of automated ftp jobs myself. I have tried several versions of this and have finally settled on a style of script that I like. I found that using a .netrc file to automate the logging-in process kept painting me into a corner because different scripts needed to sign in as different users. So I avoid .netrc and force the script to sign in. I don't like to allocate pty's unless I really am forced into it, so I also avoid pty based tools like expect. I really like ksh so that was my tool of choice. And I like the co-process concept because it makes feeding commands into the ftp process so easy with "print -p". The only problem is that the co-process manipulates standard-out so as to make it available to "read -p". And it's too hard to know how many "read -p" I will need. So I send the output to a different file descriptor. Putting it all together:

Code:
#! /usr/bin/ksh

HOST=remote.host.name
USER=whoever
PASSWD=whatever

exec 4>&1
ftp -nv >&4 2>&4 |&

print -p open $HOST
print -p user $USER $PASSWD
print -p cd directory
print -p binary
print -p put tar.gz

wait
exit 0

That script will tranfer the file and the output of the script will be the output from the ftp job itself. Put the script into cron and save the output so you can look at it the next morning.
Hi:
I tried your script .. somehow it doesnt work with SFTP it still asks for password......
#!/usr/bin/ksh
exec 4>&1
sftp user@host >&4 2>&4 |&
print -p cd outgoing
print -p put test1
wait
exit 0

Any suggestions?

dput

dput(1) 						      General Commands Manual							   dput(1)

NAME

       dput - package upload tool for Debian

SYNTAX

       dput [options] [host] package.changes ...

DESCRIPTION

       This  is  a  tool  for uploading Debian packages into the archive. You may specify to which host it should upload the file by passing it an
       host argument. If omitted, dput uses the host specified by default_host (or, historically default_host_non-us) configuration option.   Also
       you have to pass the program one or more name of package.changes files and then they will be sequentially uploaded.

       This  program  will  then  upload  the  package for you into the archive, using a selected upload method. Currently dput supports ftp, scp,
       rsync, http, https, and local. The method scripts have been split from the main script  so  it  is  easy  to  add  new  methods.   Look	in
       /usr/share/dput/ for examples.

       Should  something  go  wrong  with your upload to destinations using the Debian upload queue daemon (e.g. ftp-master), you can remove files
       from the upload queue with dcut(1).

OPTIONS

       -c, --config - define a config file to use.

       -d, --debug - activate debugging mode, helpful if bugs occur.

       -D, --dinstall - do a dry run of dinstall after the upload.

       -f, --force - force an upload of an already uploaded package.

       -h, --help - print help information and exit.

       -H, --host-list - print the lists of hosts that dput knows about.

       -l, --lintian - run lintian before the upload.

       -U, --no-upload-log - do not write a .upload log file after uploading.

       -o, --check-only - check only the package and do not upload.

       -p, --print - print the configuration that dput is using.

       -P, --passive - use passive ftp instead of active. Note that passive ftp is the default unless specified  otherwise  in	the  configuration
       file.

       -s, --simulate - simulate an upload only.

       -u, --unchecked - don't check GnuPG signature on the changes file.

       -e,  --delayed  - Upload to a DELAYED queue, rather than the usual Incoming. This takes an argument from 0 to 15. Note that a delay of 0 is
       different from no delay at all.

       -v, --version - print version information and exit.

       -V, --check-version - check if the user has already installed and tested the package before putting it into the archive.

       This program doesn't depend on any environment variables. But if the variable USER is set, it will be used.
