PID +(where PID is the process ID of +.B xvfb\-run +itself) is created in the directory specified by the environment variable +.B TMPDIR +(or +.I /tmp +if that variable is null or unset), and the +.BR tempfile (1) +command is used to create a file in that temporary directory called +.IR Xauthority . +.TP +.B \-h\fR,\fB \-\-help +Display a usage message and exit. +.TP +.BI \-n\ servernumber \fR,\fB\ \-\-server\-num= servernumber +Use +.I servernumber +as the server number (but see the +.B \-a\fR,\fB \-\-auto\-servernum +option above). +The default is 99. +.TP +.B \-l\fR,\fB \-\-listen\-tcp +Enable TCP port listening in the X server. +For security reasons (to avoid denial\-of\-service attacks or exploits), +TCP port listening is disabled by default. +.TP +.BI \-p\ protocolname \fR,\fB\ \-\-xauth\-protocol= protocolname +Use +.I protocolname +as the X authority protocol to use. +The default is \(oq.\(cq, which +.B xauth +interprets as its own default protocol, which is MIT\-MAGIC\-COOKIE\-1. +.TP +.BI \-s\ arguments \fR,\fB\ \-\-server\-args= arguments +Pass +.I arguments +to the +.B Xvfb +server. +Be careful to quote any whitespace characters that may occur within +.I arguments +to prevent them from regarded as separators for +.BR xvfb\-run 's +own arguments. +Also, note that specification of \(oq\-nolisten tcp\(cq in +.I arguments +may override the function of +.BR xvfb\-run 's +own +.B \-l\fR,\fB \-\-listen\-tcp +option, and that specification of the server number (e.g., \(oq:1\(cq) may +be ignored because of the way the X server parses its argument list. +Use the +.B xvfb\-run +option +.BI \-n\ servernumber \fR,\fB\ \-\-server\-num= servernumber +to achieve the latter function. +The default is \(oq\-screen 0 640x480x8\(cq. +.TP +.BI \-w\ delay \fR,\fB\ \-\-wait= delay +Wait +.I delay +seconds after launching +.B Xvfb +before attempting to start the specified command. +The default is 3. +.SH ENVIRONMENT +.TP +.B COLUMNS +indicates the width of the terminal device in character cells. +This value is used for formatting diagnostic messages. +If not set, the terminal is queried using +.BR stty (1) +to determine its width. +If that fails, a value of \(oq80\(cq is assumed. +.TP +.B TMPDIR +specifies the directory in which to place +.BR xvfb\-run 's +temporary directory for storage of the X authority file; only used if the +.B \-f +or +.B \-\-auth\-file +options are not specified. +.SH "OUTPUT FILES" +.PP +Unless the +.B \-f +or +.B \-\-auth\-file +options are specified, a temporary +directory and file within it are created (and deleted) to store the X +authority cookies used by the +.B Xvfb +server and client(s) run under it. +See +.BR tempfile (1). +If \-f or \-\-auth\-file are used, then the specified X authority file is +only written to, not created or deleted (though +.B xauth +creates an authority file itself if told to use use that does not already +exist). +.PP +An error file with a user\-specified name is also created if the +.B \-e +or +.B \-\-error\-file +options are specifed; see above. +.SH "EXIT STATUS" +.B xvfb\-run +uses its exit status as well as output to standard error to communicate +diagnostics. +The exit status of \(oq1\(cq is not used, and should be interpreted as failure +of the specified command. +.TP +0 +.B xvfb\-run +only uses this exit status if the +.B \-h\fR,\fB \-\-help +option is given. +In all other situations, this may be interpreted as success of the specified +command. +.TP +2 +No command to run was specified. +.TP +3 +The +.B xauth +command is not available. +.TP +4 +The temporary directory that was going to be used already exists; since +.B xvfb\-run +produces a uniquely named directory, this may indicate an attempt by another +process on the system to exploit a temporary file race condition. +.TP +5 +A problem was encountered while cleaning up the temporary directory. +.TP +6 +A problem was encountered while using +.BR getopt (1) +to parse the command\-line arguments. +.SH EXAMPLES +.TP +.B xvfb\-run \-\-auto\-servernum \-\-server\-num=1 xlogo +runs the +.BR xlogo (1x) +demonstration client inside the +.B Xvfb +X server on the first available server number greater than or equal to 1. +.TP +.B xvfb\-run \-\-server\-args="\-screen 0 1024x768x24" ico \-faces +runs the +.BR ico (1x) +demonstration client (and passes it the +.B \-faces +argument) inside the +.B Xvfb +X server, configured with a root window of 1024 by 768 pixels and a color +depth of 24 bits. +.PP +Note that the demo X clients used in the above examples will not exit on +their own, so they will have to be killed before +.B xvfb\-run +will exit. +.SH BUGS +See +.URL "http://bugs.debian.org/xvfb" "the Debian Bug Tracking System" . +If you wish to report a bug in +.BR xvfb\-run , +please use the +.BR reportbug (1) +command. +.SH AUTHOR +.B xfvb\-run +was written by Branden Robinson and Jeff Licquia with sponsorship from +Progeny Linux Systems. +.SH "SEE ALSO" +.BR Xvfb (1x), +.BR xauth (1x) +.\" vim:set et tw=80: |
