Cap apt-get download speed
apt-get is pretty aggressive when it downloads, potentially hogging the bandwidth of your network. The 25 is in KB, change this to your needs.

See system users

run command on a group of nodes in parallel redirecting outputs
Do the same as pssh, just in shell syntax. Put your hosts in hostlist, one per line. Command outputs are gathered in output and error directories.

Ultimate current directory usage command
A little bit smaller, faster and should handle files with special characters in the name.

Length of longest line of code
Here's an awk version.

Empty a file

Record your desktop
That will capture 200 seconds of video at fullscreen 1680x1050 resolution, but scaled down 25 percent, with 15 frames per second. http://fusioncast.blogspot.com/2007/09/infobyte-how-i-record-my-desktop.html

Remove any RPMs matching a pattern
This should be an option to rpm, but isn't. I wind up using it a lot because I always forget the full name of the packages I want to delete.

Run a bash script in debug mode, show output and save it on a file
Sends both stdout and stderr to the pipe which captures the data in the file 'out.test' and sends to stdout of tee (likely /dev/tty unless redirected). Works on Bourne, Korn and Bash shells.
