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’ve had nohup fail to keep things running after my session ended quite frequently. It’s like it just goes to the next step in the process then gives up.

        It’s likely that you’re using a systemd based system and the admin hasn’t enabled linger for your user.

          The servers are very locked down, so I’m sure that’s part of our compliance requirements. I haven’t looked into fixing it because I just wrote a script to hit Enter every 10 minutes to keep it alive.

            Ha! Faking key presses, truly an elegant weapon for a more civilized age. If it works, it works.

      It’s not as useful, sadly. Nohup disconnects standard input, output, and error. With screen or tmux, you can reattach them later.
