xvfb-run - run specified X client or command in a virtual X server
xvfb-run [ command ]
xvfb-run is a wrapper for the Xvfb(1) command which simplifies the task
of running commands (typically an X client, or a script containing a
list of clients to be run) within a virtual X server environment.
xvfb-run sets up an X authority file called Xauthority in the current
working directory, writes a cookie to it (see xauth(1)) and then starts
an Xvfb server as a background process using server number 99, with TCP
port listening turned off. The process ID of Xvfb is stored for later
use. After three seconds (to give the server time to initialize and
start listening for connections), the specified command is run using
the X display corresponding to the Xvfb server just started and the X
authority file created earlier. The command is also echoed to standard
output for convenience in Makefile-based invocations of. xvfb-run.
When the command exits, its status is saved, the Xvfb server is killed
(using the process ID stored earlier), the X authority cookie removed,
and the authority file deleted. xvfb-run then exits with the exit status
xvfb-run requires the xauth(1) command to function. If xauth is not
available, xvfb-run will issue an error message and exit with status
is created (and deleted) in the current working directory to
store the X authority cookies used by the Xvfb server and
client(s) run under it.
It might be nice if xvfb-run support command-line options to support
specification of the display number to use, whether TCP port listening
should be enabled in the X server, the name of the X authority file to
use, the length of the delay before the client is started, and the
keyspace of the X authority cookie (XDM-AUTHORIZATION-1 versus MITMAGIC-COOKIE-1,
