LinuxQuestions.org - Other than chmod 2***

You obviously know wrong ...

Quote:

from man chmod

Code:

      A numeric mode is from one to  four  octal  digits  (0-7),

      derived  by  adding  up  the bits with values 4, 2, and 1.

      Any omitted digits are assumed to be leading  zeros.  The

      first  digit  selects the set user ID (4) and set group ID

      (2) and save text image [`sticky']  (1)  attributes.  The

      second digit selects permissions for the user who owns the

      file: read (4), write (2),  and  execute  (1);  the  third

      selects  permissions  for other users in the file's group,

      with the same values; and the fourth for other  users  not

      in the file's group, with the same values.

I suppose you could have found that
yourself, too :)
