xkill(1X)                                               xkill(1X)



NAME
     xkill - terminates a client application

SYNOPSIS
     xkill [-display display] [-id resource] [-button number]
     [-frame] [-all]

DESCRIPTION
     xkill forces the X server to close connections to client ap-
     plications. This command is very dangerous, but is useful
     for terminating applicatons that have displayed undesired
     windows on the screen. If you do not specify an identifier
     as an argument to -id, xkill displays a special pointer as a
     prompt for you to select a window of the application you
     want to terminate. When you press the mouse button (or LEFT
     or RIGHT ARROW key) while the pointer is over a nonroot win-
     dow, the server closes its connection to the client appli-
     caiton that created the window.

   Options
     The xkill command accepts these options:

     -all    Indicates that all clients with top-level windows on
             the screen should be terminated.  The xkill command
             asks you to select the root window with each of the
             currently defined buttons to give you several
             chances to terminate.  Use of this option is highly
             discouraged.

     -button number
             Specifies the mouse button number (for a three-
             button mouse) to be used to select a window of the
             application you want to terminate. If you specify
             any, you can use any mouse button. By default, the
             first button in the pointer map, which is usually
                                                          r
             the left-most button, is used. On a Macintosh  com-
             puter, 1 is the mouse button, 2 is the LEFT ARROW
             key, and 3 is the RIGHT ARROW key.

     -display display
             Specifies the name of the X server to contact.

     -id resource
             Specifies the X identifier for the resource whose
             creator is to be terminated. If no resource is
             specified, xkill displays a special pointer with
             which you select the window of the application to
             terminate.

     -frame  Causes xkill to ignore the standard conventions for
             finding top-level client windows, which are typical-
             ly nested inside a window manager window, and to

             terminate direct children of the root window.

   X defaults
     Button  Specifies a specific mouse button number to use when
             selecting windows.  The word any allows any button
             to be used.
