aptitude cheatsheet

Hans-Henry Jakobsen — Tue, 25 Mar 2008 22:41:07 +0000

aptitude is a great alternative to apt-get and the best way to install, remove, upgrade, and otherwise administer packages on you system with apt. aptitude solves orphaned dependencies and has a curses interface that blows the doors off of dselect. Finally, and most importantly, it takes advantage of one tool, doing many many operations:

Syntax	Description
aptitude	Running it with no arguments brings up a curses based interface to search, navigate, install, update and otherwise administer packages
aptitude install	Installing software for your system, installing needed dependencies as well
aptitude -d install	Download packages to the package cache as necessary, but do not install or remove anything.
aptitude remove	Removing packages as well as orphaned dependencies
aptitude purge	Removing packages and orphaned dependencies as well as any configuration files left behind
aptitude search	Search for packages in the local apt package lists
aptitude update	Update the local packages lists
aptitude upgrade	Upgrade any installed packages that have been updated
aptitude clean	Delete any downloaded files necessary for installing the software on your system
aptitude dist-upgrade	Upgrade packages, even if it means uninstalling certain packages
aptitude show	Show details about a package name
aptitude autoclean	Delete only out-of-date packages, but keep current ones
aptitude hold	Fix a package at it’s current version, and don’t update it

aptitude uses many of the same commands as apt-get. It is not a good idea to use both, you should either use aptitude or apt-get exclusively, or your dependencies might get confused.
