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.

grep ^\# some_file

grep -v ^\# some_file

awk '!/#/' file

For the fun!

sed -n '/^#/!p' some_file
Comment by n0ky75 318 weeks ago

none of these deal w/ leading whitespace anyway. better:

awk '!/(\b)?\#/'

...dealing with trailing comments is not really practical, i guess.

Comment by wwest4 318 weeks ago

grrrr... I forgot an important piece in the description... my command doesn't display empty lines either. Whereas, things like grep -v "^#" do

@wwest4 seems you're struggling pretty hard. Maybe try testing your command in the shell before committing the comment? Further, what you ended up with doesn't certainly isn't as beautiful as the initial command. Further, '^[^#]' can be used in vim, less, sed, awk, and many programs making it beautiful.
