Hi,
I have to do a project that will combine computergraphics, AI and
scripting. I know perl can be used for AI and scripting, but how about
graphics (e.g. OpenGL)? I read the faq, but couldn't find an answer on that.
Thanks,
Huub

I'm using one simple program to launch some daemons. When I launch a
program, I use backticks. (This is all on Linux, in bash, btw.) I've
added "2>&1 >/dev/null &" to the command line, so it's like this:
`/path/to/program 2>&1 >/dev/null &`;
I've noticed that if I include the '&' so the program detaches from the
shell, if I kill the launching program, the child process survives. I've
also tried this by forking first:
if (!fork()) {
`/path/to/program 2>&1 >/dev/null &`;
exit;
}
I had the hope that if I forked and launched like this, once all the
programs were launched, the launching program would exit. It doesn't. Is
there a way I can launch a program, then have the first program exit, so
it's no longer using that bash instance (without killing it)?
Thanks!
Hal
