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 heard about helix from you and I’ve used it for a year and a half or so now, it’s by far the best editor I’ve used so far and I can definitely vouch for it

      Just commenting to give more love to helix. It’s my favorite “small quick edits” editor.

      I’ve actually been testing with fish recently coming from zsh, though I might wait until 4.0 fully releases before I make a more conclusive decision to move or not.

      With that said, I remember looking through omf themes and stumbled onto Starship that branched off one of the themes and really liked the concept.

        It does have clojure lsp support, but you’ll probably have to use a command line for most repls.

          Yeah the clojure lsp support is top notch, but there being no support for “jacking in” to a repl is the big thing keeping me from using helix full time. There’s a way of doing it if you use kitty, but it’s pretty janky.
