If you are superuser, you can remove one or more packages with the following command:
# /usr/sbin/pkgrm SUNWatm SUNWatma SUNWatmu |
In this example, the pkgrm command will remove the SUNWatm (SunATM Device Drivers and Utilities), SUNWatma (SunATM Interim API Support Software), and SUNWatmu (SunATM Runtime Support Software) packages.
