SYNOPSIS
       wpa_cli  [ -p path to ctrl sockets ] [ -g path to global ctrl_interface
       socket ] [ -i ifname ] [ -hvB ] [ -a action file ] [ -P pid file ] [ -G
       ping interval ] [ command ... ]


OVERVIEW
       wpa_cli  is a text-based frontend program for interacting with wpa_sup-
       plicant. It is used to  query  current  status,  change  configuration,
       trigger events, and request interactive user input.

       wpa_cli  can  show the current authentication status, selected security
       mode, dot11 and dot1x MIBs, etc. In addition,  it  can  configure  some
       variables  like  EAPOL state machine parameters and trigger events like
       reassociation and IEEE 802.1X logoff/logon.  wpa_cli  provides  a  user
       interface  to  request  authentication  information,  like username and
       password, if these are not included in the configuration. This  can  be
       used  to  implement,  e.g.,  one-time-passwords  or  generic token card
       authentication where  the  authentication  is  based  on  a  challenge-
       response that uses an external device for generating the response.

       The control interface of wpa_supplicant can be configured to allow non-
       root user access (ctrl_interface GROUP= parameter in the  configuration
       file).  This  makes  it  possible  to  run  wpa_cli  with a normal user
       account.

       wpa_cli supports two modes: interactive and command  line.  Both  modes
       share  the  same  command set and the main difference is in interactive
       mode providing access to unsolicited messages  (event  messages,  user-
       name/password requests).

       Interactive  mode is started when wpa_cli is executed without including
       the command as a command line parameter. Commands are then  entered  on
       the wpa_cli prompt. In command line mode, the same commands are entered
       as command line arguments for wpa_cli.

INTERACTIVE AUTHENTICATION PARAMETERS REQUEST
       When wpa_supplicant need authentication parameters, like  username  and
       password,  which  are not present in the configuration file, it sends a
       request message to all attached frontend  programs,  e.g.,  wpa_cli  in
       interactive   mode.   wpa_cli   shows   these   requests   with  "CTRL-
       REQ-<type>-<id>:<text>" prefix. <type> is IDENTITY,  PASSWORD,  or  OTP
       (one-time-password).  <id>  is a unique identifier for the current net-
       work. <text> is description of the request. In case of OTP request,  it
       includes the challenge from the authentication server.

       The  reply  to these requests can be given with identity, password, and
       otp commands. <id> needs to be copied from the matching request.  pass-
       word and otp commands can be used regardless of whether the request was
       for PASSWORD or OTP. The main difference between these two commands  is
       that  values  given with password are remembered as long as wpa_suppli-
       cant is running whereas values given with otp are used  only  once  and
       then  forgotten, i.e., wpa_supplicant will ask frontend for a new value
              CTRL-REQ-OTP-2:Challenge 1235663 needed for SSID foobar
              > otp 2 9876

COMMAND ARGUMENTS
       -p path
              Change the path where control sockets should be found.

       -g control socket path
              Connect  to  the  global  control  socket  at the indicated path
              rather than an interface-specific control socket.

       -i ifname
              Specify the interface that is  being  configured.   By  default,
              choose  the  first  interface found with a control socket in the
              socket path.

       -h     Help.  Show a usage message.

       -v     Show version information.

       -B     Run as a daemon in the background.

       -a file
              Run in daemon mode executing the action  file  based  on  events
              from  wpa_supplicant.   The specified file will be executed with
              the first argument set to interface name  and  second  to  "CON-
              NECTED"  or  "DISCONNECTED" depending on the event.  This can be
              used to execute  networking  tools  required  to  configure  the
              interface.

              Additionally, three environmental variables are available to the
              file: WPA_CTRL_DIR, WPA_ID, and  WPA_ID_STR.  WPA_CTRL_DIR  con-
              tains  the  absolute  path  to the ctrl_interface socket. WPA_ID
              contains the unique network_id identifier assigned to the active
              network,  and  WPA_ID_STR  contains  the  content  of the id_str
              option.

       -P file
              Set the location of the PID file.

       -G ping interval
              Set the interval (in seconds) at which wpa_cli pings the suppli-
              cant.

       command
              Run  a  command.   The available commands are listed in the next
