UBB.Developers Forums Community Development Programming MySQL and Server Configuration Is there any difference between CHMOD 777 and CHMOD 0777?

Actually chmod does technically have 4 digits.
I think if you leave any digits off, it's presumed to be a zero.

From: http://www.ss64.com/bash/chmod.html

The first digit is the user who owns it. (u)
The second is other users in the file's group (g)
The third is other users not in the file's group (o)
The fourth is All Users (a)
