       iwgetid - Report ESSID, NWID or AP/Cell Address of wireless network

       iwgetid [interface] [--scheme] [--ap] [--freq] [--mode]

       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.

	      This option disables pretty-printing of the information, only  the  raw  ESSID  (or
	      NWID,  or AP Address) is printed. Also, characters that are not alphanumerics (like
	      space, punctuation and control characters) are skipped.
	      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 variable in Shell or Perl scripts.

       --ap   Display the MAC address of the Wireless Access Point or the Cell.

       --freq Display the current frequency or channel used by the interface.

       --mode Display the current mode of the interface.

	      Display the protocol name of the interface. This allow 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.

       iwconfig(8), ifconfig(8), iwspy(8), iwpriv(8).
