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:

#! /usr/bin/ksh

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

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.
I tried your script .. somehow it doesnt work with SFTP it still asks for password......
exec 4>&1
sftp user@host >&4 2>&4 |&
print -p cd outgoing
print -p put test1
exit 0

Any suggestions?

I would use Perl. Any version newer that 5.0x has the necessary Net::FTP module.


use Net::FTP;

$ftp = Net::FTP->new("MACHINE_NAME", Debug => 0)
or die "Cannot connect to $@";

or die "Cannot login ", $ftp->message;

or die "Cannot change working directory ", $ftp->message;

or die "get failed ", $ftp->message;


You could then stuff this into the user cron. Hard coding the username and password does present obvious security issues. If you're interested in Perl, check out and

Thank you very much

Thank you very much for the explanation and example of this script. I had to install korn shell for the command interpreter, but at 330KB I think I can spare the diskspace.


Here is a link to my application of this.
