Questions tagged [apt]

The Advanced Packaging Tool (APT) is a package management system for Debian, and a set of tools for manipulating that system.

apt is a command-line tool used by many Linux users to manage their packages. It is used to install, update and remove packages. The most used are apt-get and apt-cache.

The most used commands are:

  • apt-get [options] install <package> which installs a program.
  • apt-cache [options] search <package> which searches for a program in case you don't know the exact name, or want to check version or any other property of the program. This is not modifying the system.
  • apt-get [options] remove <package> removes a package from the system.

Note: Most operating systems require sudo for the some commands (like the installation of packages) this is only a security measure.
