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.

      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.
