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 inte-
grate 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
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 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 se-
lector 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 ac-
cept 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.
