Adding Prefix to File name
Good old bracket expansion :-) For large numbers of files, "rename" will spare you the for-loop, or the find/exec...

Calculate days on which Friday the 13th occurs (inspired from the work of the user justsomeguy)

Sorts and compare 2 files line by line

Create a simple video contact sheet using the vcs bash script
Assumes you've downloaded Toni Corvera's vcs script (http://p.outlyer.net/vcs), have it in your PATH, and have installed the script's dependencies. Generates a video contact sheet of 24 thumbnails and 3 thumbnails per column. The bold font and white-on-black color scheme keeps the text readable at the chosen 70% JPEG compression quality, which keeps the file size at a manageable level. You can go even lower with the quality and get a good looking result.

Run a file system check on your next boot.
The empty file /forcefsck causes the file system check fsck to be run next time you boot up, after which it will be removed. This works too: $sudo >/forcefsck

tree by modify time with newest file at bottom
Go look at sample output first This is kind of like the ls command but displays by modify time with size, date and color. The newest files at the bottom of the screen (reverse using tac)

determine if tcp port is open
for udp nmap -sU -p 80 hostname

Recursively lists all files in the current directory, except the ones in '.snapshot' directory
