The following examples will demonstrate the mechanics of setting permissions using chmod in absolute mode.

Examples

This example will give the user, group, and others read only access on the ball file:

$ chmod 444 ball

$ ls -l ball

-r--r--r-- 1 chuck peanuts 1320 Oct 16 12:20 ball

$

Now we will change the permissions on ball so that user and group have write access as well:

$ chmod 664 ball

$ ls -l ball

-rw-rw-r-- 1 chuck peanuts 1320 Oct 16 12:22 ball

$
