Very Computer

If I interrupt a Linux PovRay trace with Ctrl-Z (i. e. the process is
immediately stopped) does any pixels which have been traced since the last
write-to-disk get flushed and saved?

I am asking this as I sometimes have to quickly abandon a trace via Ctrl-Z
under Linux, as the particular trace is very slow and doing Ctrl-C has me
waiting about 15 minutes for the program to exit to the shell.

I am I actually throwing away progress by Ctrl-Z 'ing out after an 18 hour
trace and NOT doing Ctrl-C and waiting the extra half an hour for PovRay to
finish in its own time the one pixel and exit? I am using an abort count of
1 already.

Thanks!

Besides, unless someone has just announced that the power was about to
be cut off, there's no reason for you to not issue a "bg" and let your
trace run in the background.

        I have a similar problem in Tampa, Florida, USA so I bought a UPS. A
cheap one mainly for the short power drops during a flash but it gives about
20 minutes on the occasion that power goes out and real surge suppression
instead of a little MOV wafer.

        If you can bring yourself to trust your computer, do the proper
interupt command for povray and just shut off your monitor. (It feels funny
at first but it works.) The UPS should last about twice as long with just
the computer and will shut down when the UPS shuts down. Then you just have
the extra time for a file check on reboot. And if you upgrade to 7.2 you get
ext3 which lets you bypass the file check on reboot.
