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.

For anyone that didn't recognise this as a joke, do not do this!
Oh. Ok. Should I undo it then?
Yeah just hit Ctrl + Z and you should be fine
Yup, this will pretty much destroy your system.
Actually curious how though - I mean won't it just let all programs/users access everything? Or do some system stuff rely on permissions for certain behavior?
SSH will definitely break, I've had this issue before. If your private key in the .ssh dir is too open, ssh won't let you use it.
I actually don't know how many programs do this, but several check that file permissions are correct or refuse to work. Sudo and ash are 2 of them. I could see /etc/shadow being readable and writable by everyone being a problem too, but I don't know.
Edit removed it. What was it?
