Linux clear command tutorial for beginners (3 examples)

Sometimes, while working on the command line, you arrive at a point where there’s too much text on the terminal screen, and none of that is relevant to you.

In this tutorial, we will be discussing the basics of clear (the tool in question) as well as how to use it.

The tool’s man page makes it amply clear (no pun here) that the only use of the tool is to clear the terminal screen. Here’s the exact definition from the man page:
