I found this post very useful.

But I had one more question I could not find the answer too. Im using mprime -b

my question is, is there a way to see the progress its making.. like the stuff it normally prints to the screen every 10,000 iterations while letting it remain in the background?

thanks

there are several ways i guess. you can pipe the output to a file ala

./mprime -b > output.file &

or you can use nohup.

"nohup ./mprime -b"

the output of the program is automatically sent to a file called nohup.out. hope this helps.

i tried
"nohup ./mprime -b"
let it run for about 2 hours and the file was 0bytes
killed mprime and then tried
./mprime -b > output.file &
and the file is also 0bytes... probably cause there is nothing to pipe cause the -b hides all output?

any other alternatives?
thanks

Try the -d command line argument

does the -d flag work with the -b flag? Im still not having any luck.
I access this machine remotely so it has to be in the background, im just nosey and like to see the progress/speeds from time to time.
thanks

The -b suppresses the output. Use & to put it in the background instead, i.e. "./mprime -d &" or "nohup ./mprime -d &".
