Make vim open in tabs by default (save to .profile)
I always add this to my .profile rc so I can do things like: "vim *.c" and the files are opened in tabs.

Generate a Random MAC address

Watch and cat the last file to enter a directory
Great for watching things like Maildir's or any other queue directory.

Write a bootable Linux .iso file directly to a USB-stick
Writes hybrid ISO directly to USB stick; replace /dev/sdb with USB device in question and the ISO image link with the link of your choice

Consolle based network interface monitor
ethstatus part of ethstatus package, is a consolle based monitor for network interfaces. Nicely display on screen a real time summary about bandwidth, speed and packets.

find files in a date range
Find files in a specific date range - in this case, the first half of last year. -newermt = modification time of the file is more recent than this date GNU find allows any date specfication that GNU date would accept, e.g. $ find . -type f -newermt "3 years ago" ! -newermt "2 years ago" or $ find . -type f -newermt "last monday"

Launch a game, like Tetris, when apt-get installing an app larger than 50 Megabytes
Change the APP variable's value to whatever you want to install. Depending on how fast your machine is, you'll want to adjust the value 50 to something else. You might also want to play a different game than Gnometris - just make sure it's a GUI game.

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.

convert a web page into a png
This requires the command-line print extension (see #2861 for more details). I use it to make up complex images with formatted text using CSS and whatnot. It's a lot slicker than imagemagick for certain things. Now imagine using a local webserver with PHP and a database to generate the images. Oh, the possibilities...
