You can also use '''octal numbers''' to represent permissions. This method may require less typing than using the symbolic method.
Since 1 octal digit represents 3 binary digits, one octal digit can represent the <span style="font-family:courier;font-weight:bold;">rwx </span> permission granted or NOT granted. The permissions rwz would be in the form of 3 binary digits (1 represents the permission granted and 0 represents the permission NOT granted.
'''NOTE:''' You can only use this method to '''set''' file permissions (as opposed to ''add'' or ''remove'' permissions).
