System Administration Commands                         getdev(1M)



NAME
     getdev - lists devices based on criteria

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


DESCRIPTION
     getdev generates a list of devices that match  certain  cri-
     teria.  The criteria includes 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 criteria are included in the generated list. How-
     ever, if the -e option is used, the list becomes  a  set  of
     devices  to  be  excluded  from  the  list. See  OPTIONS and
     OPERANDS.

OPTIONS
     The following options are supported:

     -a    Specifies that a device must match all criteria to  be
           included  in  the  list generated by this command. The
           option 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 gen-
           erated by this command. Without the -e the named  dev-
           ices  are included in the generated list. The flag has
           no effect if no devices are defined.


OPERANDS
     The following operands are supported:

     criteria    Defines the criteria that a device must match to
                 be  included  in the generated list. criteria is
                 specified by expressions.

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