commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Numeric zero padding file rename

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".

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
ls *.jpg | awk -F'.' '{ printf "%s %04d.%s\n", $0, $1, $2; }' | xargs -n2 mv

rename file name with fixed length nomeric format pattern

for i in $(seq -w 0 100) ; do mv prefix$(( 10#$i )).jpg prefix${i}.jpg ; done

Know a better way?

If you can do better, submit your command here.

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: http://linux.die.net/man/1/rename

This one is really useful, and found its way in my .bash_aliases .

(the *.jpg replaced with $@ obviously...)
