What's this?

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.

If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

Universal configuration monitoring and system of record for IT.

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.

mmv most likely must be installed, but is very powerfull when you want to move/copy/append/link multiple files by wildcard patterns.

for f in *.txt;do mv ${f%txt}{txt,md}; done

Same thing using bash built-in features instead of a sub-shell.

for f in *.txt; do mv $f `basename $f .txt`.md; done;

This version of rename mrwill is referring to comes from the package util-linux-ng, a collection of utilities for linux development.

On the other hand, the rename you're trying to execute comes from Larry Wall and is basically a Perl wrapper.

Some Linux distributions install both of them, usually the first one as 'linux.ul' and the second as 'rename'. Obviously, this is the situation for Juev when trying to execute rename(1).
