List processes playing sound
When trying to play a sound you may sometimes get an error saying that your sound card is already used, but not by what process. This will list all processes playing sound, useful to kill processes that you no longer need but that keep using your sound card.

Create Encrypted WordPress MySQL Backup without any DB details, just the wp-config.php
The coolest way I've found to backup a wordpress mysql database using encryption, and using local variables created directly from the wp-config.php file so that you don't have to type them- which would allow someone sniffing your terminal or viewing your shell history to see your info. I use a variation of this for my servers that have hundreds of wordpress installs and databases by using a find command for the wp-config.php file and passing that through xargs to my function.

Do one ping to a URL, I use this in a MRTG gauge graph to monitor connectivity

Freshening up RKhunter
Not everyone reads manpages. Aliasing this command will help with the task of doing audits with RKhunter. It will check for the latest version, update the definitions and then run a check on the system. Hint: alias that in your .bashrc to make life for your fingers easier.

Shows you how many hours of avi video you have.
midentify.sh is part of mplayer, but you might have to locate it on your box.

Advanced python tracing
Trace python statement execution and syscalls invoked during that simultaneously

List of computers not logged into in more than four weeks

Find out current working directory of a process
This is an alternative to another command using two xargs. If it's a command you know there's only one of, you can just use: $ ls -l /proc/$(pgrep COMMAND)/cwd

Picture Renamer
jhead is a very nice tool to do all sorts of things with photographs, in a batch-oriented way. It has a specific function to rename files based on dates, and the format I used above was just an example.
