UNITS is a program which gives status information on disk drives.
The status information shows, among other things, what units are being
used and their logical relationships if any.
The program can be used to rapidly get pertinent information on
mounted structures and available drives. Additionally, if there is status
information on the drive, a comment will be made to that effect at the end
of the line describing that drive.
There are no program commands. In order to use the program, a user
must have WHEEL or OPERATOR capability.
To use simply type
$UNITS or RU UNITS
