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/

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.

Counts number of lines (in source code excluding comments)

I took java to make the find command simpler and to state that it works for any language supported by cpp.

cpp is the C/C++ preprocessor (interprets macros, removes comments, inserts includes, resolves trigraphs). The -fpreprocessor option tells cpp to assume the input has already been preprocessed so it will only replace comment lines with blank lines.

The -L 1 option tells xargs to launch one process for each line, indeed cpp can only process one file at the time...

Know a better way?

If you can do better, submit your command here.

What others think

You don't need grep . in there. `xargs wc -l` works just fine.

Why is this useful? Looking to brag about the amount of code you've written? Hoping to impress your boss on the next yearly review? LOC mean nothing to your ability as a programmer.

find . -name '*.php' | xargs wc -l

says the total is 1564, but

find . -name '*.php' | xargs grep . | wc -l

says it is 1161...

@atopnce: indeed but code volume can be an interesting information, for instance when you've just been handed a code to maintain
