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
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. However, if the -e option is used, the
list becomes a set of devices to be excluded from the list.
criteria defines
the criteria that a device must match to be included in the generated list.
Should be specified by giving expressions.
device defines the devices which
should be included in the generated list. This can be the pathname of the
device or the device alias.
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.
- -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 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.
The command will exit with one of the following values:
- 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.
- /etc/device.tab
