description
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.
