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

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

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
       device doesn't have any ESSID it will print its NWID.

OPTIONS
       --scheme
              This  option  disables  pretty-printing of the information, only
              the raw ESSID (or NWID, or AP Address) is printed. Also, charac-
              ters  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 vari-
              able 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.

       --protocol
              Display  the protocol name of the interface. This allow 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.
