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 used nano when I started but now I am using vim for one year already. I’d recommend taking a few days where you only use vim and I think you will see why people like it. With a few motions you can be much faster than you would be in Nano.

I’m using Linux since 1998 and still like nano. I can use vi, but prefer nano when it’s available.
