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.
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.
