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.
OpenDoas, or simply doas, as in do [command] as [user]
Thanks, couldn’t get it ever to work tho, and it doesn’t come with a default config in Arch.
Because it’s so simple, a good default config can be a one-liner. For similar functionality to default sudo:
Allows members of
wheelto run commands as any user (if you just rundoas <cmd>it will default to root), and “persists” for 5 minutes, ie if you run doas then for the next 5 minutes in the same session you won’t have to enter your password to run doas again, similar to default sudo settings.https://wiki.archlinux.org/title/Doas
What problems were you having where you couldn’t get it to work?
Always got permission denied, no matter what in the config. But thanks, i’ll try again.
