Check These Out

check open ports without netstat or lsof

Signals list by NUMBER and NAME
This command seems to achieve the similar/same goal.

Find dead symbolic links

Random unsigned integer
Reads 4 bytes from the random device and formats them as unsigned integer between 0 and 2^32-1.

replace spaces in filenames with underscores
This command will replace all the spaces in all the filenames of the current directory with underscores. There are other commands that do this here, but this one is the easiest and shortest.

Find longest running non-root processes on a machine
If you have ever been trying to look for a list of processes based on their elapsed time you don't need to look any further. This command lets you find the list of processes ordered in a reversed order (oldest at the top) that have been running for over an hour on your system. Any system processes are filtered out, leaving only user initiated ones in. I find it extremely useful for debugging and performance analysis.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Change pidgin status
Thanks for the comment oshazard, i wasn't aware of purple-remote existence.

List your largest installed packages.
Requires the "wajig" package to be installed.
