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.

    true delivers error level 0, false error level 1.

    yes && echo True || echo False will always be True.

    false && echo True || echo False will always be False.

    Common usage is for tools that ask for permissions and similiar. yes | cp -i has the same effect as cp --force (-i: prompt before overwrites).
