4.7.5.4 Adding Members to a Class

To add a process to a class, you use the add command as shown in the

following interactive mode example:

class> add batch_jobs uid 234 457 235

Note that you must use one of the unique identiﬁers previously speciﬁed

and you cannot add the same identiﬁer to a class more than once. The same

procedure can be performed in command mode or from a script as follows:

# class_admin add batch_jobs uid 234 457 235

uid 234 457 235 added to high_users

In command mode, additions to a class are automatically saved to the

/etc/class database.

4.7.5.5 Deleting Members From a Class

To delete one or more processes from a class, use the delete command in

interactive or command mode. For example:

class> delete high_users uid 11

uid 11 deleted from high_users

This example deletes the single UID number 11 from class high_users.
