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’ve used Vim for some pretty non-nerdy stuff. Like ripping my DVD collection, when I got to the TV section I had a lot of file names to modify in bulk, and Vim let me do that. Also guitar tablature, the ability to edit plaintext both horizontally and vertically is surprisingly handy. Just having a macro to be able to add a bar line saves a shocking amount of time.
It was mostly a joke. I was just trying to mess with people 😉
Which I’ll use as a lighthearted excuse to mention things like the block edit mode.
