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.

PortsInfo is a simple desktop app that shows a list of active network ports on your linux systems.

In other words, it shows you which servers are running on your computer.

It's a graphical equivalent of running netstat -plunt in a terminal.

The app supports quick search with CTRL+F shortcut.

Hopefully this will be useful to newbies and system administrators.

BootSelector is a tiny GUI utility for setting any grub menu entry as default.
