iwgetid - Report ESSID, NWID or AP/Cell Address of wireless network
iwgetid [interface] [--raw]
[--scheme] [--ap] [--freq]
"[--mode][--protocol][--channel]
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.
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.
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.
Display the MAC address of the Wireless Access Point or the Cell.
Display the current frequency or channel used by the interface.
Display the current channel used by the interface. The channel is determined using the current frequency and the frequency list provided by the interface.
Display the current mode of the interface.
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.
