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.
Tmux is so much better than screen, and yes that is the hill I will die on
Specially when confined with tmuxp , it’s how I handle Game servers that can run headless to start at boot without losing access to giving commands to the server via its server console
