What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. 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.

Share Your Commands

Check These Out

display a smiling smiley if the command succeeded and a sad smiley if the command failed

you could save the code between if and fi to a shell script named smiley.sh with the first argument as and then do a smiley.sh to see if the command succeeded. a bit needless but who cares ;)

From Vim, run current buffer in python

Find usb device in realtime

Using this command you can track a moment when usb device was attached.

Watch the progress of 'dd'

The 'dd' command doesn't provide a progress when writing data. So, sending the "USR1" signal to the process will spit out its progress as it writes data. This command is superior to others on the site, as it doesn't require you to previously know the PID of the dd command.

Synchronise a file from a remote server

You will be prompted for a password unless you have your public keys set-up.

put current directory in LAN quickly

iso-8859-1 to utf-8 safe recursive rename

This command is a powerful "detoxifier" that eliminates special chars, spaces and all those little chars we don't like. It support several "sequences" so be sure to check your /usr/local/etc/detoxrc while at it... and maybe define your own

Install pip with Proxy

Installs pip packages defining a proxy

dont log current session to history

move you up one directory quickly

In bash, this turns on auto cd. If a command is just a directory name, it cd's into that directory.

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.
