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.

String Capitalization

Helpful when we want to do mass file renaming(especially mp3s).


There are 7 alternatives - vote for the best!

Terminal - Alternatives

Know a better way?

If you can do better, submit your command here.

What others think

perl has uc, lc, ucfirst, etc. That's much more graceful than the awk there.

@linuxrawkstar, Then you have somewhat bigger dependency(perl is bigger than awk).

Comment by BlockerT 304 weeks and 4 days ago

Yeah but these days disk space is cheap. On debian lenny, the base perl package takes 12MB. In that package is the perl rename script 'prename' (usually rename is a symlink to this) which lets you specify a perl regex for file renaming. See 'man prename' for more.

echo "${STRING}" | tr a-z A-Z

enough to do that?

Comment by Josay 304 weeks and 3 days ago

Nope. The toupper only capitalizes the first letter of the substr.
