Aptitude command

Like Apt-get, Aptitude is the most powerful package management tool in Debian and its derivative systems. Unlike Apt-get, aptitude is better at dealing with dependency issues. For example, when aptitude deletes a package, it also deletes the packages it depends on. This way, the system will not be left with useless packets, the whole system is cleaner. The following is a summary of some of the common aptitude commands, for reference only.

Aptitude update updates the list of available packages
Aptitude Upgrade Upgrade Available packages

Aptitude Install Pkgname installation package
Aptitude Remove Pkgname Delete Package
Aptitude Purge Pkgname Delete package and its configuration file

Of course, you can also use aptitude in text interface mode.
