Apt Command in Linux

apt is a command-line utility for installing, updating, removing, and otherwise managing deb packages on Ubuntu, Debian, and related Linux distributions. It combines the most frequently used commands from the apt-get and apt-cache tools with different default values of some options.

apt is designed for interactive use. Prefer using apt-get and apt-cache in your shell scripts as they are backward compatible between the different versions and have more options and features.

Most of the apt commands must be run as a user with sudo privileges.

This guide serves as a quick reference for the apt commands.
