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.

Somehow convinced a person to run
sudo chmod -x /usr/bin/*
I don't remember the exact command so it could be a bit different but it did the job. It was a fun evening.
The first time I read this, i thought "shouldn't all that be executable anyway?"
And then I read it again and realized, minus x
An intern nuked their workstation by
sudo chmod -R 777 /
. Turns out adding exec to everything isn't good either.Daaem, I guess the poor dude at the receiving end did not consider it particularly fun. Well, at least they had sbin working, so probably possible to recover without a live cd. Huh, guess who's now spinning up a VM to check it out 🤣
Checked it out: on arch that results in inability to run tty on reboot, then you're dropped into initramfs's rescue shell where you can simply +x new_root's /usr/bin/* and be back up and running
