Check These Out

list files recursively by size

Blank/erase a DVD-RW

bash screensaver (scrolling ascii art with customizable message)
Displays a scrolling banner which loops until you hit Ctrl-C to terminate it. Make sure you finish your banner message with a space so it will loop nicely.

tcpdump whole packets to file in ascii and hex with ip adresses instead of hostname

Change mysql prompt to be more verbose
You can put this into your shell sourced file like .bashrc or .zshrc to have a different mysql prompt. See http://dev.mysql.com/doc/refman/5.1/de/mysql-commands.html for more informations. Beware that currently with mysql 5.5 the seconds are buggy and won't be displayed if you put this into a .cnf file. With the enironment variable this will work.

List the Sizes of Folders and Directories
I wanted an easy way to list out the sizes of directories and all of the contents of those directories recursively.

command line calculator
simple function , floating point number is supported.

List all groups and the user names that were in each group
"cut" the user names from /etc/passwd and then running a loop over them.

Get Cisco network information
This gives you lots of nifty Cisco network information like VLAN tag, port and switch information.

Create a tar archive using 7z compression
Using 7z to create archives is OK, but when you use tar, you preserve all file-specific information such as ownership, perms, etc. If that's important to you, this is a better way to do it.
