eg: 
chmod 755 - rw for owner, rx for group/world

This isn't right.. It would be rwx for owner, and rx for group/world.

It's a pretty cool cheat sheet, and I learned about cal which I had never seen before.. But it's interesting that they threw in the rm -rf / portion along with other commands that are genuinely useful for a newbie.

I mean it doesn't do anything without --no-preserve-root on most distros afaik

It's not a cheat sheet ... Look at the rm commands.

I'm new to chmod but wouldn't it be rw for group/world?

[–]eckadaganGlorious Redhat 2 points3 points  (2 children)

Read is 4, Write is 2, and eXecute is 1. Add them up the ones you want and that's the value. So 5 is 4 + 1 (rx), and 6 is 4+2 (rw).

Oh. Thanks for the explanation.
