Few useless scripts which can help in particular tasks:

• compare.py - recursively compares two directories, doing diffs with files, printing deleted or added files/categories etc.
• filecase - change case of filenames/directories (GREAT -> small, small -> GREAT or swap case)
• perms - recursively apply permissions, different to files and to directories
• genpass.py - generate random password
• mke.py - GUI for create custom keybindings in Metacity. Just execute, no arguments required.
• killer.pl - show process table (result of ps), and allow to send any signal to selected processes via browser
• wwwshell.php - simple php script to execute shell command (usefull when your hosting doesn't provide shell...)
• sat.pl - simple tool for static analysis
