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.
Wow, who hurt you? Vim is fun, and just because you can make things work without it doesn’t mean it has no practical benefit. It’s nice to have an editor as powerful as an IDE that doesn’t require a graphical environment.
Hundreds of shortcuts is emacs, by the way. A major perk of modal editing and the vi editing language is that you can compose relatively few operations to accomplish many tasks rather than memorizing lots of more complex and specific shortcuts.
