Check These Out

Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

Connect to all running screen instances
There was another line that was dependent on having un-named screen sessions. This just wouldn't do. This one works no matter what the name is. A possible improvement would be removing the perl dependence, but that doesn't effect me.

"Pretty print" $PATH, separate path per line
from: http://www.unix.com/shell-programming-and-scripting/28047-split-print-path.html

Terminal - Prints out, what the users name, notifyed in the gecos field, is

coloured shell prompt
This coloured prompt will show: username in green, grey "@" sign, hostname in red, current directory in yellow, typed commands in green.

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"

Destroy all disks on system simultaneously
This command will use the fdisk utility to find all block devices on your system, and overwrite them with data from the /dev/urandom non-blocking random number generator. CAUTION: This will irrevocably erase EVERY SINGLE physical block storage device visible to the fdisk utility, including plugged USB devices, RAID sets, LVM, etc.

Generate an XKCD #936 style 4 word passphrase (fast)
Some snippets posted are slow on big dictionaries, this one is fast.

Send email with one or more binary attachments
This command uses mutt to send the mail. You must pipe in a body, otherwise mutt will prompt you for some stuff. If you don't have mutt, it should be dead easy to install.

Compare two directory trees.
