in reply to Shell Commands executed in perl script

You have quotes inside your quotes. Try the following:

print $sh->ls( qq(-l ./logs/ |grep -v "^d" |grep -v file1 | awk 'NR>1 +{ print \$9}'));

Or indeed you could use q() as you're not doing any variable substitution inside the string.

Update: yes I know it would be better for the OP to have coded this in perl rather than shelling out 4 subprocesses. Sometimes you need to start with where the person is. Spotting the quote nesting is something glaringly obvious to me - a kind of mistake anyone can make in coding, and worth pointing out.

    Dude ... Do you really need to use Shell at all ??? Convert this shell to perl code...will probably take less time then debugging this errors one at a time.
