CLI
Abbreviation for Command Line Interface
In short and in plain language
A CLI lets you run software by typing text commands.
You type commands into a line instead of clicking on buttons.
This way, upkeep tasks can run by themselves. They can be repeated in the same way.
Examples are clearing the cache or putting in updates.
Definition
A CLI is a way of operating software through text commands in a command line instead of a graphical interface. Maintenance tasks such as clearing the cache or applying updates can be run this way in an automated and repeatable manner.
