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 and sed have always been intimidating for me with that cryptic syntax.
I agree with your sentiment regarding confusing syntax, however I think that confusion simply requires a calculated approach to dispell it.
It’s a prime example of why I use scripts as reminders as much as I use them functionally. I work out the syntax once… save it to an example script, then save myself 20 minutes of remembering by just $ cat ./path/to/script.sh and copying said syntax.
So if you can change your workflow such that learned things stay around as examples, I feel that you will pick it up much more quickly :)
