Swap is a space on a disk that is used when the amount of physical memory is full. When a Linux system runs out of RAM, inactive pages are moved from the RAM to the swap space.

Swap space can take the form of either a dedicated swap partition or a swap file. Usually, when running a Debian virtual machine a swap partition is not present so the only option is to create a swap file.

This tutorial will guide you through the steps of adding a swap file on Debian 10 Buster. weiterlesen

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.

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.
