or
Code:
ssh user@host exec /bin/sh -s arg1 arg2 arg3 < local-shellscript.sh

In Perl you can just dump those raw into system(), which of course will wait, but you can
Code:
use POSIX ":sys_wait_h";

...

$pid=fork();
if($pid == 0)
{
        exec("ssh user@host command1 ';' command2");
        die "exec failed";
}

# parent will continue here without waiting for the child.
# you can check periodically with
if(waitpid($pid, WNOHANG) > 0)
{
        print "Child finished with status $?\n";
}

I see and understand the concept to an extent, but it doesn't look like this code can assign the output of the commands to variable within my perl script. If this is not the case, please explain.

Thanks.
