Numeric zero padding file rename

rename 's/\d+/sprintf("%04d",$&)/e' *.jpg
This uses Perl's rename utility (you may have to call it as prename on your box) and won't choke on spaces or other characters in filenames. It will also zero pad a number even in filenames like "vacation-4.jpg".

What Others Think

This command does not work unless you have your 'rename' command aliased to the perl script that comes with the Debian 'perl' package. Unless you're using Debian or a derivative, you're more likely to have the 'rename' command described here:

This one is really useful, and found its way in my .bash_aliases . (the *.jpg replaced with $@ obviously...)
