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  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 attri-
                       bute is defined and is equal to value.

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

     attribute:*       Selects all devices which have the  attri-
                       bute attribute defined.

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

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

  Options and Arguments
     The options and arguments for this command are:

     -a                Specifies that a  device  must  match  all
                       criteria  to  be included in the list gen-
                       erated 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 dev-
                       ices are included in the generated  list.)
