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.

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.

dust: better version of du. There's also diskonaut which is an interactive tool.

On the subject of editors, joe is just awesome: lightweight, powerful, had coffee coloring and line numbers, and you can choose it with Ctrl+C:)

ia: internetarchive https://archive.org/developers/internetarchive/cli.html cli tool, i only use it for downloads, it can a bit more than the eye meets first, like accepting a wildcard to download certain files or specify other stuff. I have an incomplete script to help me with that, which I want to share in the future. The only problem is, that the internetarchive at archive.org is often very slow at downloading.

+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.
