Burn an audio CD.
My variation on an audio burning command from commandlinefu - this one doesn't crap out if you want to burn a CD in a directory whose permissions don't allow it, and instead rips everything to /tmp. If you mount your music partition like I do using Samba, you probably don't have write permission inside that file system in order to create the temporary directory other audio burning commands here use. Not a bad idea to add cdrom to your groups, and /bin/eject with visudo.

Rsync two directories with filtered extensions

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Get file access control list

Gets the last string of previous command with !$
It helps you save a lot of writing :-)

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

Color STDERR in output
This command will take the output of a command and color any STDERR output as a different color (red outline in this case)

Numbers guessing game
Felt like I need to win the lottery, and wrote this command so I train and develop my guessing abilities.
