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.

      Cant remember exactly but it had something to do with a file relating to sudo and it only was allowed to be edited with a vim style editor.

        The EDITOR or VISUAL environment variables are usually read by command line tools to launch your preferred editor. You could set VISUAL to nano before launching visudo and you would be editing the sudoers file in nano.

        There may be certain times where it’s all that’s available, I think I remember having to edit fstab in some recovery state in vi

        /etc/sudoers?

        you can just edit that with nano or whatever, the visudo thing they tell you to use is goofy and I don’t like it
