Is there a man page for the file permission numbers?
I'm specifically talking about
r = 4
w = 2
x = 1
I can never remember them and I have to google it every time I need to set permissions besides 755. I don't think I'm alone, either, since there's even a site that calculates the number for you.
I just realized the man page for chmod
doesn't have any description of the numbers and I can't figure out what other page would have them. I guess an info
page would work as well, since apparently it comes pre-installed (I have arch; I'd have thought I'd have had to install that one myself--apparently not). It would be a lot easier for me if I could just refer to an 'on-line' man page (I use 'on-line' in the sense used in man man
).
ls -l
output that "rwx" order eventually gets stuck in your mind :-)
