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.

I'm a big fan of screen because it will let me run long-running processes without having to stay connected via SSH, and will log all the output.

I do a lot of work on customers' servers and having a full record of everything that happened is incredibly valuable for CYA purposes.

nohup is similar

I've had nohup fail to keep things running after my session ended quite frequently. It's like it just goes to the next step in the process then gives up.

It's likely that you're using a systemd based system and the admin hasn't enabled linger for your user.

The servers are very locked down, so I'm sure that's part of our compliance requirements. I haven't looked into fixing it because I just wrote a script to hit Enter every 10 minutes to keep it alive.

Ha! Faking key presses, truly an elegant weapon for a more civilized age. If it works, it works.
