====== Ubuntu - apt ======

**apt** stands for Advanced Package Tool; to install, delete or remove apps, keep the system up to date with security patches and more.

  * apt does not provide all package options, but provide the most commonly used ones.
  * See [[Ubuntu:apt-get|apt-get]] which provide a lot more options, which may be more confusing to the end-user.

The `apt` command is meant to be pleasant for end users and does not need to be backward compatible like apt-get.
