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 find myself using tldr a lot since finding out about it. It’s just so useful for commands that I don’t use enough to commit to memory.
What is it?
You type tldr and then some command. For example, tldr tar. It gives you a small list of examples and common use cases for the command.
