a) How do octal access control codes work?


b) How do you set access controls with command line options instead of octal codes?

What are you working with?
Try this:
Ascii Table - ASCII character codes and html, octal, hex and decimal chart conversion

Strat, this question is a follow-up to Unix controls.

The Wikipedia article I referenced in Unix controls covers this. What isn't clear?

See the chmod command man page or the man page on your system, particularly the parts regarding specifying the parameters of the command using symbolic mode. Only root or the file's owner can make changes. Example: chmod u=rwx MyFile.
