I just installed POV-Ray on my linux box and it is rendering a scene right
now. I have a question. Is there a way to get it to display the approximate
percentage complete (like the Windoze version)?

Right now it is just sitting there "Rendering..."

I have no graphical display, just text, as I am telnetting to it from my Win
machine. Not enough room in here for two monitors, two keyboards, and two
mice. Really.

Also, the reason I did it this way is so my wife or I could use the Win
machine while I have something rendering on the Linux machine. Is there a
way to let it render in the background, even if I am not currently
telnetted/logged into the machine?

Thanks in advance for any help.

Try +V in the command line.

This sounds like a typical use of the "detached" process. To get the
render to proceed "in the background" (actually, as a separate
process detached from the controlling terminal), precede your
POV-Ray invocation with the word "nohup" and follow it with
" > /dev/null &", as in the following example:

nohup s-povray +Iinput.pov > /dev/null &

The "nohup" tells Linux to continue the process even after
the original login process terminates (i.e. after you log
off), the "> /dev/null" redirects standard-output to a
null file so it doesn't clutter up the terminal, and the
trailing "&" (ampersand) causes the process to detach from
the terminal from which you start it, running as a
separate process. Of course, this will remove the "progress
indication" you were wanting, as it does not output to the
terminal during this time, but it will run the render in
the background.

Hope this helps.

I did, no progress indication. Not *too* big a deal really, just would be
nice to see.

Very odd, it works on my computer, I wonder what's going wrong.  Sorry I can't
be of more help.

  +v works in both Linux and Solaris here. It should work there too.

Hmm ... I'll try it again when I get home. At work right now. Thanks.

Another and IMO easier way would be to use the package screen. 

screen -S povray
will create a new 'screen' called 'povray' this is just another shell
basically, in here you start the render, or whatever you want, then
press ctrl+a,d to jump away from that screen. 
this can afterwards be resumed(to watch output and other things) by
using screen -r povray
screen is a rather handy lil' prog that i tend to use a lot (either
local or remote computers)

Well, over and out .

Hmmm... this does sound handy, and sounds like something I wish
I had on our SCO machine at work (into which I dial occasionally).
However, I had never heard of that. Just checked, and apparently
this is not something that's a default part of Linux (at least,
not RH6). You know the old saying... "go with what you know best". :)
