The Aardvark Shell Utils is a collection of three utilities designed to aid the user when working with shell scripts or from the command line. All three accept input on the command line or from standard input, and thus they can be piped with other commands. All commands come with their own man page. Included are realpath, filebase, and fileext.

BleachBit deletes junk to recover disk space and maintain privacy. It rids your system of old junk including cache, Internet history, temporary files, unused locale files (better than localepurge), logs, and cookies. Designed for Linux systems, it wipes clean 50 applications including Adobe Reader, Bash, Firefox, Flash, OpenOffice.org, Opera, Real Player, Skype, and more. It shreds files so that they cannot be recovered, and it wipes free disk space to hide insecurely deleted files. It offers both a simple PyGTK GUI and a command line interface for automation.
