When using symbolic mode to set
permission, you typically work with one category of users, although
you can give all categories the same permissions simultaneously. The
mode is referred to as relative since you are assigning or removing
permissions relative to the ones that are already there. You can add
one or more permissions to a specific group or take them away. The command format for
symbolic mode uses letters and symbols. Roll your mouse over Figure
for additional information.
| Command Format: |
| chmod mode

The mode portion of the command
format is made up
of three parts:
- Who - Category of users you
are working with (u, g, o or a)
- Op - Operator or what you are
going to do, set (=), remove (-), give (+)
- Permissions - Permission(s)
assigned - Read (r), Write (w) or Execute (x)
