terminal-based package manager aptitude is a terminal-based package manager with a number of useful features, including: a mutt-like syntax for matching packages in a flexible manner, dselect-like persistence of user actions, the ability to retrieve and display the Debian changelog of most packages, and a command-line mode similar to that of apt-get. aptitude is also Y2K-compliant, non-fattening, naturally cleansing, and housebroken.
