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/

Get involved!

You can sign-in using OpenID credentials, or register a traditional username and password.

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.

What others think

This is a good place to note that the dividers on a sed substitute construct can be almost anything. It doesn't have to be a `/`


sed "s_\([a-zA-Z]*\:\/\/[^ ]*\)\(.*\)_\<a href=\"\1\"\>\1\<\/a\>\2_"


Since you have all that "picket fencing" ( `\/` ) and escaping of the parentheses this version will improve the readability.

I agree with unixmonkey365 and suggest to further use single quotes, here.

sed 's|\([a-zA-Z]*://[^ ]*\)\(.*\)|<a href="\1">\1</a>\2|'
