rename 's/\d+/sprintf("%02d",$&)/e' -- $@
2013-02-14 18:29:18
User: Vilemirth
Functions: rename

Uses 'rename' to pad zeros in front of first existing number in each filename. The "--" is not required, but it will prevent errors on filenames which start with "-". You can change the "2d" to any number you want, equaling the total numeric output: aka, 4d = ????, 8d = ????????, etc.

I setup a handful of handy functions to this effect (because I couldn't figure out how to insert a var for the value) in the form of 'padnum?', such as:

padnum5 () {

/usr/bin/rename 's/\d+/sprintf("%05d",$&)/e' -- $@


Which would change a file "foo-1.txt" to "foo-00001.txt"

fdupes -r .

If you have the fdupes command, you'll save a lot of typing. It can do recursive searches (-r,-R) and it allows you to interactively select which of the duplicate files found you wish to keep or delete.

find . -type d -exec mkdir /copy_location/{} \;
rm *[!abc]

Bash method to remove all files but "abc".

It would be 'rm *~abc' in Zsh.
