Which Linux command or utility is simple, powerful, and surprisingly unknown to many people or used less often?

This could be a command or a piece of software or an application.

For example I’m surprised to find that many people are unaware of Caddy, a very simple web server that can make setting up a reverse proxy incredibly easy.

Another example is fzf. Many people overlook this, a fast command-line fuzzy finder. It’s versatile for searching files, directories, or even shell history with minimal effort.

    Use less for checking contents of files. Many people use cat all the time, but I don’t like it, because if you do that often, your terminal window quickly gets flooded with stuff, and then you have to scroll up and down if you wanna see a previous output. With less, your file opens in a different “frame”, which you can close when you’re done.
