XKILL(1)                FreeBSD General Commands Manual               XKILL(1)

       xkill - kill a client by its X resource

       xkill [-display displayname] [-id resource] [-button number] [-frame]

       Xkill is a utility for forcing the X server to close connections to
       clients.  This program is very dangerous, but is useful for aborting
       programs that have displayed undesired windows on a user's screen.  If
       no resource identifier is given with -id, xkill will display a special
       cursor as a prompt for the user to select a window to be killed.  If a
       pointer button is pressed over a non-root window, the server will close
       its connection to the client that created the window.

       -display displayname
               This option specifies the name of the X server to contact.

       -id resource
               This option specifies the X identifier for the resource whose
               creator is to be aborted.  If no resource is specified, xkill
               will display a special cursor with which you should select a
               window to be kill.

       -button number
               This option specifies the number of pointer button that should
               be used in selecting a window to kill.  If the word "any" is
               specified, any button on the pointer may be used.  By default,
               the first button in the pointer map (which is usually the
               leftmost button) is used.

       -all    This option indicates that all clients with top-level windows
               on the screen should be killed.  Xkill will ask you to select
               the root window with each of the currently defined buttons to
               give you several chances to abort.  Use of this option is
               highly discouraged.

       -frame  This option indicates that xkill should ignore the standard
               conventions for finding top-level client windows (which are
               typically nested inside a window manager window), and simply
               believe that you want to kill direct children of the root.

       This command does not provide any warranty that the application whose
       connection to the X server is closed will abort nicely, or even abort
       at all. All this command does is to close the connection to the X
       server. Many existing applications do indeed abort when their
       connection to the X server is closed, but some can choose to continue.

       Button  Specifies a specific pointer button number or the word "any" to
               use when selecting windows.
