RTFM function

Some commands have more information on 'info' than in the man pages

shows history of logins on the server

outputs a history of logins on the server (top 10, when piped to 'head'); optional flags: '-a' put the hostname at the end of the line (good for long hostnames), '-i' post the IP instead of the hostname, '-F' put the full login and logout times, rather than short times.

Get your outgoing IP address

Given a file path, unplug the USB device on which the file is located (the file must be on an USB device !)

You have an external USB drive or key. Apply this command (using the file path of anything on your device) and it will simulate the unplug of this device. If you just want the port, just type : echo $(sudo lshw -businfo | grep -B 1 -m 1 $(df "/path/to/file" | tail -1 | awk '{print $1}' | cut -c 6-8) | head -n 1 | awk '{print $1}' | cut -c 5- | tr ":" "-")

Colorize make, gcc, and diff output

Colorize output of make, gcc/g++ or diff, making it easier to read at a glance. They are not distributed with make, diff or gcc, but are usually available in the repositories.

Matrix Style

Same as the cool matrix style command ( http://www.commandlinefu.com/commands/view/3652/matrix-style ), except replacing the printed character with randomness. The command mentioned is much faster and thus more true to the matrix. However, mine can be optimized, but I wasted ... i mean spent enough time on it already
