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

Useful for checking if there are differences between local and remote files.

vimdiff <file> scp://[<user>@]<host>/<file>
vimdiff scp://[user@]host1/<file> scp://[user@]host2/<file>

A little messy, but functional. Requires vim >= 7.x.

test "$(md5sum /local/file | cut -d' ' -f1)" == "$(ssh [email protected] -- md5sum /remote/file | cut -d' ' -f1)" && echo "Match" || echo "Differ"

Functions: echo test

This method does not transfer the contents of the entire file, instead it computes a md5 sum of the file on each end so that large files can be compared without transferring them across the net.

diff <(ssh $remote_site cat $file) $file

User: hal8
Functions: cat diff ssh

opens the output of some command as a file so this also works with graphical editors like meld, kdiff3 etc

meld <(ssh $remote_site cat .zshrc) .zshrc
