xwait - Wait until an X Window is created or mapped.
xwait [-map] [-title TITLE] [-class CLASS] [command [command arguments]]
xwait waits for creation of an X window by listening to events on the root window. It returns after either a CreateNotify event or a MapNotify (by specifying --map) event have been received. The received events may be filtered further by specifying a window title or class name via the --title and --class options.
Optionally, xwait can execute a command after setting up the event filter to avoid race conditions.
-print : Print the matched window ID to stdout before exiting
-pid PID
: Override the parent PID to match for the newly created window. Overriding with 0 disables the check.
-map : Wait for MapNotify events instead of CreateNotify events. The MapNotify event is fired when a window is mapped to the screen to be displayed, while CreateNotify only indicates that a window exists.
-title TITLE : Wait for a window of a specified title instead of reacting to just any window.
-class CLASSNAME : Wait for a window of a specified class name instead of reacting to just any window.
command [command arguments] : Execute a command after starting the event listener. Using this functionality avoids race conditions between starting xwait and an event source.
Returns 0 on success and other values on error.
DISPLAY has to be set, obviously.
