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.

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Runs previous command but replacing

Really useful for when you have a typo in a previous command. Also, arguments default to empty so if you accidentally run:

echo "no typozs"

you can correct it with

^z

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
!!:s/foo/bar/

Replaces the first instance of 'foo' with 'bar'. To replace all instances of 'foo' with 'bar': !!:gs/foo/bar/

Know a better way?

If you can do better, submit your command here.

What others think

^foo^bar replaces first instance of foo. If you want to replace multiple instances of a string, then you should use:

!!:s/foo/bar/g
Comment by alperyilmaz 388 weeks ago
!!:s/foo/bar/g

Won't work in bash. Instead, use:

!!:gs/foo/bar
Comment by fletch 387 weeks and 6 days ago

^foo^bar does not work in mksh

Comment by penpen 386 weeks and 4 days ago

Works fine in bash!!

ex:

~$ lq -ltra

lq: command not found

~$ ^lq^ls

ls -ltra

Comment by unixmonkey8946 335 weeks and 2 days ago

Short notation for replaces all instances of foo with bar:

^foo^bar^:&
Comment by Testuser_01 233 weeks and 6 days ago

I think it's safer to reload the command and edit it

Comment by scavenger 195 weeks and 2 days ago
!!:gs/^foo^bar

this one is what i want

btw,i want to kown how to reload the command and then edit it in an easy way like in vim ...

Comment by byrgl5 170 weeks and 3 days ago

@byrgl5

You can do this in bash. All You need is to put: "set -o vi" somewhere in your .bashrc and create .inputrc with following content (without line numbers of course :P):

1 "\e[A":history-search-backward

2 "\e[B":history-search-forward

3 set editing-mode vi

4 set keymap vi
