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.

Delay execution until load average falls under 1.5

If shell escaping of the command is problematic, you can write the command to a file first: $ batch

Indent a one-liner.

I often write a one-liner which I want to use later in a script.

write by vim need root privilege

Write comments to your history.

A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Record camera's output to a avi file

video.avi is the resulting file. Press Ctrl+c to stop the recording. You can change the OVC option to another to record into a different format.

Add timestamp to history

History usually only gives the command number and the command. This will add a timestamp to the history file. Note: this will only put the correct timestamp on commands used after the export is done. You may want to put this in your .bashrc

vmstat/iostat with timestamp

Also useful with iostat, or pretty much anything else you want timestamped.

How to check network connection from one interface

This command only check the network connection from given eth. This is very useful if you are using more then one interface in your server or laptop.

Shows all packages installed that are recommended by other packages

Shows the packages installed on your system that are recomemnded by other packages. You should remove these packages.

Run a long job and notify me when it's finished

You will need libnotify-bin for this to work: $ sudo aptitude install libnotify-bin
