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.
There are minor feature differences there’s also a convenience factor: youtube-dl people for some reason stopped doing releases, so you can’t get a fresh version from pypi (only installing from github or their site). Yt-dlp is on pypi, including nightly builds.
