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.
It’s for people that don’t want a big bulky IDE and are willing to put a little work in to get used to it. I do all my coding in the terminal with vim and tmux and I like the simplicity and that with two dotfiles I can migrate my whole development environment to whatever PC, server or RaspberryPi that I need.
