Maybe I'm missing something, but I cannot believe that this is as
difficult as it is being made out to be. I do this all the time with
computationally intensive programs. Simply let it run in background by
putting the ampersand after the command e.g.
myprogram &
or
./myprogram &
if . is not in your path. The fact that it is so easy to do this is the
main reason I switched from NT to Linux. That and the fact that I can
remotely log in and restart jobs from home or on the road. Try that in
NT! Unix is the environment where real work gets done. If your program
sends stuff to STDOUT (i.e. the screen) and you want to see all of that
later then
myprogram > screendump &
then all of the screen output will be dumped into a file called
screendump for your later review.
Regarding not finding the process in ps. Well, you won't find it there,
'cause ps shows processes that are running that were started by the
terminal you are currently logged into (a little know fact). To prove it,
while in X, log into two xterms. From one start a program in background
(e.g. emacs &). Now from that xterm type ps. There is emacs listed. Now
run ps from the other xterm. Huh? emacs isn't found. Now run top. Ah Ha,
there is emacs.
There may be a switch that allows you to use ps to see all processes
started by you (your username) but off the top of my head I wouldn't know
what it is. You should be able to see your process in top though. That
shows all of the processes running on the machine. That list will be much
longer, but it should be in there (provided it didn't finish running
while you were away).
Happy computing
