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.

That's all fine and dandy, but why does it say rxw on the left?
Permissions are listed as "user", "group", "other". I.e. the user who made the file, the group of the user who made the file (usually just their name as a group), and everyone else. In this case the rxw is for the user.
For chmod, you can also represent these as binary numbers: 111 would mean having all 3, 101 would mean having read and write, etc. These binary numbers then get turned back into regular numbers (7 in the first example, since it's 111) for chmod. Giving a file "chmod 777" means the user, group, and other all have full permissions on the file. "chmod 700" gives the creator full control, but no one else can view, modify, or execute the file.
It's supposed to be rwx, not rxw.
Oh I completely missed that lol. Oh well, it's probably still a useful explanation for someone else reading this
I feel bad for you because you were just trying to help.
🤷♂️ They're just internet points, lemmy doesn't notify about up/downvotes so I will only see it if people respond. Either way it's hopefully still useful to someone else looking at the post who isn't familiar with basic permissions or acl
Read, extend, whitelisted
Read, Write, eXecute.
The guide has w and x switched on the left side
