XTOOLWAIT(1)XTOOLWAIT(1)NAMExtoolwait - start X client and wait for it to map a window
SYNOPSISxtoolwait [ -display display-name ] [ -timeout nseconds ] [ -mappings
nwindows ] [ -pid ] [ -help ] [ -version ] command
DESCRIPTION
Xtoolwait notably decreases the startup time of an X session by reduc‐
ing the load on the X server and the OS. Xtoolwait starts the X client
command in the background. It then waits until a window is mapped on
the root window and exits. Xtoolwait also exits if a time-out occurs
(by default after 15 seconds), or if command exits.
OPTIONS-display display-name
Monitor the X display display-name for window mapping events.
If this option is not used, the X display defaults to the value
of the DISPLAY environment variable. See also section NOTES
below.
-timeout nseconds
Use a time-out period of nseconds seconds. If this option is not
used, the time-out period defaults to 15 seconds.
-mappings nwindows
Exit after nwindows windows have been mapped, instead of the
default of one window. Use this option only if you are abso‐
lutely sure that command will map nwindows top-level windows, in
which case it will slightly increase the performance.
-pid Print the process id (pid) of command to standard output. This
option is useful for shell scripts that want to wait for (or
send a signal to) command. To support shell command substitution
(`command`), Xtoolwait redirects the standard output of command
to standard error.
-help Print out the `Usage:' command syntax summary.
-version
Print out the version number.
USAGE
This is the relevant part of my own .xinitrc file, showing the proper
use of Xtoolwait:
#
# Startup the window manager first
#
olvwm & wmpid=$!
#
# Restore desktop settings
# Do _not_ put xtoolwait in the background
#
xtoolwait-mappings 2 contool -Wp 30 30 -Ws 575 246 -WP 3 533 -Wi
xtoolwait xeyes -geom 77x60+640+107
xtoolwait ansi_xterm -geom 80x24+22+11
xtoolwait clock -Wp 90 90 -Ws 150 150 -WP 733 110 -Wi
#
# Wait for the window manager
#
wait $wmpid
Note that the window manager must be started first. Xtoolwait depends
on it to detect window mappings. The first instance of Xtoolwait will
wait until both the window manager and the X client have finished their
initialization.
Note also that the first Xtoolwait uses the -mappings option to detect
the virtual desktop window, which is mapped by virtual window managers.
Omit this option if you use a non-virtual window manager.
EXIT STATUS
Xtoolwait returns 0 if it detected the mapping of a window on the root
window, and 1 otherwise. The one exception to this rule is when command
exits normally before mapping a window, in which case its return value
is returned.
ENVIRONMENT
DISPLAY
The default display name to monitor
SEE ALSOxtoolplaces(1)NOTES
Xtoolwait does not propagate the -display option to command. If you
use this option, you should feed it both to Xtoolwait and to command.
This is intentional, so don't report this as a bug.

BUGS
Xtoolwait tries to ignore windows that are mapped by other X clients.
The method used will fail if two or more X clients are started almost
simultaneously. This situation does not arise as long as all X clients
are started by Xtoolwait during the X session startup.
