slashdot.org webserver adds an X-Bender or X-Fry HTTP header to every response!
Open a ssh session opened forever, great on laptops losing Internet connectivity when switching WIFI spots.

bnd-ips.txt is a list of IP adresses that is concenated for use as regular expression. Yes, this is still very speedy ;=)
use find to grep all .c files from the target directory, cat them into one stream, then piped to wc to count the lines
The command `cat file >> file` failes with the following error message:

This will launch and irssi session on your server. If it's not running, it will create the session. If it's running it'll connect to it and destroy any other connections. If compositing is available, the rxvt window will have transparency added. This window will also open maximized. Anything else this does should be easily figured out in the man pages.
On a Gentoo system, this command will tell you which packets you have installed and sort them by how much space they consume. Good for finding out space-hogs when tidying up disk space.
Should work on all systems that use dpkg and APT package management.
