Edit condition in BASH

Question

why does not work this condition?

if [ -d /home/virt -a $(ls -A /home/virt/) = 0 ]

Exists of directory /home/virt AND check if the directory is /home/virt/ empty

Thank you...

look at the output of `ls -A /home/virt/` when it's NOT empty ... OR for that matter if empty, then result is equiv to "", not 0. Won't work. Good luck. — shellter, Aug 30 '12 at 17:07
