Check These Out

send kernel log (dmesg) notifications to root via cron
this is helpful because dmesg is where i/o errors, etc are logged to... you will also be able to see when the system reboots or someone attaches a thumb drive, etc. don't forget to set yourself up in /etc/aliases to get roots email.

Make the Mac OS X Dock 2D once more (10.5 and above only)
Mac OS X 10.5 (Leopard) introduced a new, 3D, reflective Dock. For those of us who prefer the Dock to be a little less distracting, this command is the answer. The Dock will be rendered in the same style as when pinned to the left- or right-hand side of the screen. Replace YES with NO to restore the 3D Dock.

list block devices
Shows all block devices in a tree with descruptions of what they are.

install all archive file type apps in ubuntu

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"

Number of .... indicate how far down to cd
Use dots to cd down directories instead of having to remember all of the pesky back slashes! Better yet, works on even and odd number of dots! Now, just estimate how far down you want to traverse.

Video thumbnail
Faster thumbnail creation than '-itsoffset' $ffmpeg -itsoffset -4 -i test.avi -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 test.jpg

Determining the excat memory usages by certain PID
this command gives you the total number of memory usuage and open files by the perticuler PID.

Slow down the screen output of a command
(example above is the 'ls' command with reduced output speed)

grab all commandlinefu shell functions into a single file, suitable for sourcing.
Much simpler but not as many features as the alternative.
