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.”

        When tmux was first released I was already so used to screen that I never really considered switching. What would some convincing arguments be for me to make the effort to switch now?

          Tmux was purpose built for terminal multiplexing. You can assign session names for organizing and manipulating multiple instances. Send keys to and read output from detached sessions. It’s easy to script.
