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.

+1 to caddy. There are some services that set safe headers following the recommendations outlined by Mozilla but others don't control headers as strictly. Caddy is the only web server that I found that supports loose default header values. These values will be selected unless the upstream application specifies their own values.

You can do something similar in nginx but it requires playing with maps and has a little more indirection than I'd like.

Just wish caddy was capable of starting as root and stepping down permissions like Nginx. I have certs being managed by other tools and have to make sure they are installed and chowned for caddy's use when they are cycled.

I just started the process of switching from nginx Proxy Manager to Caddy yesterday, and even before setting up a single rule, I'm enjoying it more than NPM. Really wish I would have heard about it sooner!

I'm currently using NPM and don't have any problems with it for at least my use case. Is there something I'm missing out on never having tried Caddy, or is it one of those no need to switch if there's Nothing bugging you situations? That last bit is how I feel about Bazzite on the Steam Deck when people ask of they should switch.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
