Linux 2.6 - man page for iwgetid (linux section 8)

IWGETID(8)			    Linux Programmer's Manual			       IWGETID(8)

       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.

       --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.

	      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.

	      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.

	      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.

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