NAME
iwgetid - Report ESSID, NWID or AP/Cell Address of wireless network
SYNOPSIS
iwgetid [interface] [--raw] [--scheme] [--ap] [--freq]
[--mode] [--protocol] [--channel]
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 de-
vice 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 op-
tion 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 ar-
gument 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 charac-
ters).
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 selec-
tor 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 iden-
tify 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 sup-
porting Wireless Extension are mandated to support.
