getdev(1M)                       DG/UX 5.4.2                      getdev(1M)


NAME
       getdev - lists devices based on criteria

SYNOPSIS
       getdev [-ae] [criteria ...] [device ...]

   where:
       criteria  An expression defining criteria that a device must match to
                 be included in the generated list
       device    A device pathname or device alias specifying which devices
                 should be included in the generated list

DESCRIPTION
       Getdev generates a list of devices that match certain criteria.  The
       criteria includes a list of attributes (given in expressions) and a
       list of devices.  If no criteria is given, all devices are included
       in the list.

       Devices must satisfy at least one of the criteria in the list unless
       the -a option is used.  Then, only those devices which match all of
       the criteria in a list will be included.

       Devices which are defined on the command line and which match the
       criteria are included in the generated list.  However, if the -e flag
       is used, the list becomes a set of devices to be excluded from the
       list.

   Criteria Expression Types
       There are four possible expression types which the criteria specified
       in the criteria argument may follow:

       attribute=value   Selects all devices whose attribute attribute is
                         defined and is equal to value.

       attribute!=value  Selects all devices whose attribute attribute is
                         defined and does not equal value.

       attribute:*       Selects all devices which have the attribute
                         attribute defined.

       attribute!:*      Selects all devices which do not have the attribute
                         attribute defined.

                         See the putdev(1M) manual page for a complete
                         listing and description of available attributes.

   Options
       The options for this command are:

       -a     Specifies that a device must match all criteria to be included
              in the list generated by this command.  The flag has no effect
              if no criteria are defined.

       -e     Specifies that the list of devices which follows on the

              command line should be excluded from the list generated by
              this command.  (Without the -e the named devices are included
              in the generated list.)  The flag has no effect if no devices
              are defined.

FILES
       /etc/device.tab

DIAGNOSTICS
       The command will exit with one of the following values:

       0 =    Successful completion of the task.

       1 =    Command syntax incorrect, invalid option used, or internal
              error occurred.

       2 =    Device table could not be opened for reading.
