Rename files in batch

Convert files from DOS line endings to UNIX line endings
The old dos2unix from sysutils has been deprecated on Debian systems to this tool.

renice by name

commandline dictionary
Note: 1) Replace 'wonder' with any word you looking the meaning for in the above example 2) Need to install these packages: wordnet & wordnet-base (latter should be automatically installed because of dependency) 3) Combined size of packages is about 30MB on my old ubuntu system (I find it worth it)

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

Convert numbers to SI notation
converts any number on the 'stdin' to SI notation. My version limits to 3 digits of precious (working with 10% resistors).

Inverted cowsay
It's quite fun to invert text using "flip.pl" (ref: http://ubuntuforums.org/showthread.php?t=2078323 ). Slightly more challenging is to flip a whole "cowsay". :-)

Find
A lot of X applications accept --geometry parameter so that you can set application size and position. But how can you figure out the exact arguments for --geometry? Launch an application, resize and reposition its window as needed, then launch xwininfo in a terminal an click on the application window. You will see some useful window info including its geometry.

Matrix Style
I like the fact the Patola's version uses only ones and zeros, but I also like the sparse output of the other versions. This one combines both of those features and eliminates some unnecessary cruft. You can vary the sparseness by changing "$(($RANDOM % 5))" to another number. The number in this term "$(($RANDOM % 4))" controls how frequently the numbers are output bold.

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"
