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.

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.

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

Remove everything except that file

Terminal - Remove everything except that file
ls | egrep -v "[REGULAR EXPRESSION]" | xargs rm -v

Remove everything except that file

This is a slight variation of an existing submission, but uses regular expression to look for files instead. This makes it vastly more versatile, and one can easily verify the files to be kept by running ls | egrep "[REGULAR EXPRESSION]"


There are 3 alternatives - vote for the best!

Terminal - Alternatives
rm !(*.foo|*.bar|*.baz)
2010-04-13 15:13:54
User: hutch
Functions: rm

Deletes all files in a folder that are NOT *.foo, *.bar or *.baz files. Edit the pattern inside the brackets as you like.

rm -f !(survivior.txt)
find . ! -name <FILENAME> -delete

Functions: find
Tags: files rm

it will remove everything except the file names matching you can use also use wildcards

( shopt -s extglob; rm !(<PATTERN>) )
2010-01-13 16:43:15
User: sputnick
Functions: rm
Tags: files rm glob shopt

Remove everything except that file with shell tricks inside a subshell to avoid changes in the environment.

help shopt
rm !(file_to_keep_undeleted)
2010-12-15 13:31:06
User: strzel_a
Functions: rm

Go to tmp :

cd /tmp; mkdir retmp; cd retmp

Create 10 files :

for i in {1..10}; do touch test$i; done

Remove all files except test10 :

rm !(test10)

Know a better way?

If you can do better, submit your command here.

What others think

In zsh, this is easy:

rm ^filename

the caret indicates logical negation. That is my second favorite feature of zsh. The first is the ability to share history between running shell instances, and not have them clobber each other when exiting. (I'm pretty sure bash doesn't do this.)
