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.

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.

doesn't do case-insensitive filenames like iname but otherwise likely to be faster

find . -name "*.[ch]" -exec grep "TODO" {} +

-exec works better and faster then using a pipe

grep -r --include=*.php "something" /foo/bar

Actually grep can do recursive search based on file extensions.

Know a better way?

If you can do better, submit your command here.

What others think

"-iname" might be a better way to go instead of the case sensitive "-name"

you could launch multiple instances of grep in parallel if you're grepping many files:

find . -name "*.[ch]" | xargs -P $NUMCPUS grep "TODO"
