What's the simplest (and/or most concise) way to check for an empty directory?
if test -z `ls foo` ; then wibble ; fi
Or
if [ -z `ls foo` ] ; then wibble ; fi
There's probably other ways....
Just a quick note - in bash, and any real posix shell, it's (generally) better form to use $(command) than `command`, it's more readable and is nestable if needed...
Mr Pashley has a few things to say about backticks, it's worth a quick read if nothing else: http://www.davidpashley.com/blog/programming/shell/backticks.html
