sudo
is telling the computer to do this with root privileges.chmod
sets permissions.- Each digit of that three-digit number corresponds to the owner, the group, and other users, respectively. It’s 0–7, where 0 means no access and 7 means access to read, write, and execute. So
077
is the exact inverse of700
, where077
means “the owner cannot access their own files, but everyone else can read, write, and execute them”. Corresponding700
to asexuals is joking that nobody but the owner can even so much as touch the files. /
is the root directory, i.e. the very top of the filesystem.- The
-R
flag says to do this recursively downward; in this case, that’s starting from/
.
So here, we’re modifying every single file on the entire system to be readable, writable, and executable by everyone but their owner. And yes, this is supposed to be extremely stupid.
Something Happened, the other, far lesser-known work by Catch-22 author Joseph Heller. It’s too apples-to-oranges to throw around “better”, but I already love Catch-22 and still prefer Something Happened. It’s considerably longer, but in my opinion, it’s criminally overlooked.
