XKILL(1) X Version 11 XKILL(1) NAME xkill - kill a client by its X resource SYNOPSIS xkill [-display displayname] [-id resource] [-button number] [-frame] [-all] [-help|-version] DESCRIPTION Xkill is a utility for forcing the X server to close connections to clients. This program is very dangerous, but is useful for aborting pro- grams that have displayed undesired windows on a user's screen. If no re- source 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. 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 cre- ator 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 speci- fied, 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 sev- eral chances to abort. Use of this option is highly discouraged. -frame This option indicates that xkill should ignore the standard conven- tions 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. -help This option makes xkill print a usage message and exit without killing anything. -version This option makes xkill print its version and exit without killing anything. CAVEATS This command does not provide any warranty that the application whose con- nection 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 ex- isting applications do indeed abort when their connection to the X server is closed, but some can choose to continue. XDEFAULTS Button Specifies a specific pointer button number or the word "any" to use when selecting windows.
