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 just started the process of switching from nginx Proxy Manager to Caddy yesterday, and even before setting up a single rule, I’m enjoying it more than NPM. Really wish I would have heard about it sooner!
I’m currently using NPM and don’t have any problems with it for at least my use case. Is there something I’m missing out on never having tried Caddy, or is it one of those no need to switch if there’s Nothing bugging you situations? That last bit is how I feel about Bazzite on the Steam Deck when people ask of they should switch.
