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
   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.

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
          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.

   --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
          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.
