Question

We recently got SSH setup on our Windows boxes so we could eliminate the need for disc mounts on our Linux machines. We are using Pentaho and I am writing a shell script that will, from a Linux box, SSH into the Windows box and execute a perl script.

I have able to write in a way to SSH into the windows box and switch to the directory that holds the Perl scripts that I need to execute, I just can’t figure out how to actually execute them.

This is what I have:

#!/bin/sh
ssh -t xxxxx@xxxxx "cd /path/to/script/ /path/to/perl.exe HelloWorld.pl"

I have also tried:

#!/bin/sh
ssh -t xxxxx@xxxxx "cd /path/to/directory/with/perl/script" \
                   "/path/to/perl.exe HelloWorld.pl"

Both attempts result in a short delay and then a “disconnected from xxxxx” and the perl does not run. I can do all of these steps manually through a shell, but can’t seem to get them working in script form. As a note, the only way I’ve been able to execute the perl scripts is if have the shell in the directory the perl script is in.

You need to use either a semi colon to end your statements, or execute with one statement.
try the following:

ssh xxxxx@xxxxx "cd /path/to/script/; /path/to/perl.exe HelloWorld.pl"

or:

ssh xxxxx@xxxxx "/path/to/perl.exe /path/to/script/HelloWorld.pl"
