I'm using the display command to post a picture of several configurations for a machine operator to choose from. The Issue I have is when I display the image the displayed image steals focus from my bash window. The operator then has to re-select the window to answer the prompt. The other issue I have is terminating the display. I had to kill the pid. Is there a more elegant way to do this?
Thanks

pid=`ps -e|grep display|cut -f1 -d" "`
kill -9 $pid
echo $an

xshowtrace
XSHOWTRACE(1) General Commands Manual XSHOWTRACE(1)NAME
xshowtrace - interactively show rays traced on RADIANCE image under X11
SYNOPSIS
xshowtrace [ -s ][ -T ][ rtrace options ] octree picture
DESCRIPTION
Xshowtrace takes a RADIANCE octree and a picture file and displays it on an X11 window server using ximage(1). The picture should have
been created from a previous rpict(1) or rvu(1) calculation using the given octree. Once the image is displayed, the user can use the 't'
command of ximage to select points on the image to display the ray tree. Rtrace then produces a ray tree, which xshowtrace will display
(in red on a color screen). The -s option slows the display of each ray traced to make it easier to follow the process. The -T option
traces rays to light sources, which are normally hidden.
AUTHOR
Greg Ward
BUGS
If the pointer is moved between the time 't' is pressed and xshowtrace starts drawing rays, the rays will be displaced.
