XKILL(1)

NAME
       xkill - kill a client by its X resource

SYNOPSIS
       xkill  [-display displayname] [-id resource] [-button num-
       ber] [-frame] [-all]

DESCRIPTION
       Xkill is a utility for forcing the X server to close  con-
       nections  to clients.  This program is very dangerous, but
       is useful for aborting programs that have displayed  unde-
       sired  windows on a user's screen.  If no resource identi-
       fier is given with -id, xkill will display a special  cur-
       sor  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.

OPTIONS
       -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 spe-
               cial 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 win-
               dow manager window), and simply believe  that  you
               want to kill direct children of the root.

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