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.
awk
…for parsing the output of other commands quickly and simply. Then that parsed output can be used to create simple log messages or be passed as args to other scripts. Powerful.
awk and sed have always been intimidating for me with that cryptic syntax.
