getdev(1M) System Administration Commands getdev(1M)NAMEgetdev - lists devices based on criteria
SYNOPSISgetdev [-ae] [criteria...] [device...]
DESCRIPTIONgetdev 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 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 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 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.
