apt: The Package Manager on Debian-based Systems
According to APT (software) - Wikipedia, apt stands for Advanced Package Tool. I often forget the commands, so I’m compiling them here as a reference.
Note that apt-get and apt-cache are commands built for specific purposes, while apt is the CLI command for using those tools interactively.
