getdev(1M)                                                       getdev(1M)

NAME
     getdev - lists devices based on criteria

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

DESCRIPTION
     getdev generates a list of devices that match certain criteria. The
     criteria include a list of attributes (given in expressions) and a
     list of devices. If no criteria are 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 cri-
     teria 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 attri-
                         bute attribute defined.

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

OPTIONS
     -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 com-
               mand 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.

     criteria  Defines criteria that a device must match to be included in

     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.
