Thanks a lot! I've been looking for such command a few weeks ago and
couldn't find it. I had to use these ugly C++ daemons related things...
I've got another one question: how can I disable the output (stdin and
stderr) of the program? Should I redirect it to ">/dev/null" or how?
Is the "nohup" and "/dev/null" exist on all *nix systems?
