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 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 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 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.
