The apt is a command used on Debian, Ubuntu and other Linux distribution. It provides a high-level commandline interface for the package management system. It is intended as an end user interface and enables some options better suited for interactive usage by default compared to more specialized APT tools like apt-get command and apt-cache command.

           upgrade | full-upgrade | edit-sources | {-v | --version} | {-h | --help}}
