   Iwlist is used to display some additional information from  a  wireless
   network  interface  that  is  not  displayed  by iwconfig(8).  The main
   argument is used to select a category of information,  iwlist  displays
   in  detailed  form  all information related to this category, including
   information already shown by iwconfig(8).


          Give the list of Access Points and Ad-Hoc cells  in  range,  and
          optionally  a  whole  bunch  of  information  about them (ESSID,
          Quality, Frequency, Mode...). The type of  information  returned
          depends on what the card supports.
          Triggering  scanning  is  a privileged operation (root only) and
          normal users can only read left-over scan results.  By  default,
          the way scanning is done (the scope of the scan) is dependant on
          the card and card settings.
          This command takes optional arguments, however most drivers will
          ignore  those.  The  option essid is used to specify a scan on a
          specific ESSID. With  some  card/driver,  this  enables  to  see
          hidden  networks.  The  option  last does not trigger a scan and
          read left-over scan results.

          Give the list of available frequencies in  the  device  and  the
          number  of defined channels. Please note that usually the driver
          returns the total number of channels and  only  the  frequencies
          available  in  the  present  locale,  so  there is no one-to-one
          mapping between frequencies displayed and channel numbers.

          List the bit-rates supported by the device.

          List the  encryption  key  sizes  supported  and  list  all  the
          encryption keys set in the device.

   power  List  the  various  Power Management attributes and modes of the

          List the various Transmit Powers available on the device.

   retry  List the transmit retry limits and retry lifetime on the device.

          Give the list of Access Points  in  range,  and  optionally  the
          quality  of  link  to  them.  This  feature  is obsolete and now
          deprecated in  favor  of  scanning  support  (above),  and  most
          drivers don't support it.
          Some  drivers  may use this command to return a specific list of
          Peers  or  Access  Points,   such   as   the   list   of   Peers
          associated/registered   with   the   card.   See   your   driver
          documentation for details.

   event  List the wireless events supported by the device.

   auth   List the WPA authentication parametes curently set.

          List all the WPA encryption keys set in the device.

   genie  List the Generic Information Elements set in  the  device  (used
          for WPA support).

          List the modulations supported by the device and the modulations
          currently enabled.

          Display the version of the tools, as well as the recommended and
          current Wireless Extensions version for the tool and the various
          wireless interfaces.

   --help Display short help message.
