iwgetid
is used to find out the NWID, ESSID or AP/Cell Address of the wireless
network that is currently used. The information reported is the same
as the one shown by
iwconfig, but iwgetid
is easier to integrate in various scripts.
By default,
iwgetid
will print the
ESSID
of the device, and if the device doesn't have any ESSID it will print
its
NWID.
The default formatting output is pretty-print.
OPTIONS
--raw
This option disables pretty-printing of the information. This option
is orthogonal to the other options (except
--scheme),
so with the appropriate combination of options you can print the raw
ESSID, AP Address or Mode.
This format is ideal when storing the result of iwgetid as a
variable in
Shell
or
Perl
scripts or to pass the result as an argument on the command line of
iwconfig.
--scheme
This option is similar to the previous one, it disables
pretty-printing of the information and removes all characters that are
not alphanumerics (like space, punctuation and control characters).
The resulting output is a valid Pcmcia scheme identifier (that may be
used as an argument of the command
cardctl scheme).
This format is also ideal when using the result of iwgetid as a
selector in
Shell
or
Perl
scripts, or as a file name.
--ap
Display the MAC address of the Wireless
Access Point
or the
Cell.
--freq
Display the current
frequency
or
channel
used by the interface.
--channel
Display the current
channel
used by the interface. The channel is determined using the current
frequency and the frequency list provided by the interface.
--mode
Display the current
mode
of the interface.
--protocol
Display the
protocol name
of the interface. This allows to identify all the cards that are
compatible with each other and accept the same type of configuration.
This can also be used to
check Wireless Extension support
on the interface, as this is the only attribute that all drivers
supporting Wireless Extension are mandated to support.
