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.
Why should I use a sudo alternative?
Because sudo is best suited for server administration, way overengineered (with the occasional critical vulnerability) for desktop use.
Alternatives can fit the required functionality for desktop use in 150 loc C code while sudo has what, something over 100’000 loc?
