∟What Is APT

This section provides a quick introduction on APT (Advanced Package Tool), which is the default software package manager on Ubuntu computers.

What Is APT? - APT (Advanced Package Tool) is the default package manager on Ubuntu computers. It allows you to:

You can get a list of DNF commands by running "apt help" on Ubuntu: 

herong$ apt help

apt 1.6.17 (amd64)
Usage: apt [options] command

apt is a command line package manager and provides commands for
searching and managing as well as querying information about packages.
It provides the same functionality as the specialized APT tools,
like apt-get and apt-cache, but enables options more suitable for
interactive use by default.

Most used commands:
  list - list packages based on package names
  search - search in package descriptions
  show - show package details
  install - install packages
  remove - remove packages
  autoremove - Remove automatically all unused packages
  update - update list of available packages
  upgrade - upgrade the system by installing/upgrading packages
  full-upgrade - upgrade the system by removing/installing/upgrading pac...
  edit-sources - edit the source information file

Actually, "apt" combines sub-commands from both "apt-get" and "apt-cache" commands as shown below. 

apt install  = apt-get install
apt update   = apt-get update  
apt upgrade  = apt-get upgrade   
apt remove   = apt-get remove  
apt search   = apt-cache search 
apt show     = apt-cache show 
apt list

If you want to manage software packages in scripts, you should use "apt-get" and "apt-cache" commands, which return more predictable outputs.
