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.

    I’m a big fan of screen because it will let me run long-running processes without having to stay connected via SSH, and will log all the output.

    I do a lot of work on customers’ servers and having a full record of everything that happened is incredibly valuable for CYA purposes.

      I’d recommend tmux for that particular use. Screen has a lot of extras that are interesting but don’t really follow the GNU mentality of “do one thing and do it well.”
