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.

Delete the previous entry in your history

I rarely need this, but I have a hard time remembering the command when I need it.

Admit it. This has happened to you. Yes this is bad, and you better clean up now.

Know a better way?

If you can do better, submit your command here.

What others think

Very interesting. There is a way to simplify it, though.

First alter the alias to only delete one entry:

alias histdel='history -d $((HISTCMD-1))'

Now the clever bit. Add 'histdel' the the list of commands that are ignored by the history:

export HISTIGNORE=$HISTIGNORE:hd

This means histdel doesn't need to delete itself from the history and you can still run it as many times as you like.

Note: I also have aliases to show my history, which don't add to the history.

@flatcap: Very good. I think I like yours better. You should post that as an alternative.
