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/

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.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

This is a quick way to find what is hogging disk space when you get a full disk alert on your
monitoring system. This won't work as is with filesystems that allow embedded spaces in user

left-most column is PID, middle is virtual memory being consumed, right-most is actual process.
If we've many files containing (?, ?, ?, ?, ? ) characters instead of ?, ?,... etc,...

I tried a few curses based mp3 players for playing back choir practice songs for my wife.

Btrfs reports the inode numbers of files with failed checksums. Use `find` to lookup the file names of those inodes. The files may need to be deleted and replaced with backups.
