xkill - kill a client by its X resource
] [-id resource
number] [-frame] [-all] [-version]
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
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.

select the root window with each of the currently defined buttons to give
you several chances to abort. Use of this option is highly

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 option makes xkill print its version and exit without
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.
