Sorry for all the threads. I am almost done. I ahve a bash script that is launching a diags program then copying the .html over my client. then it does the following line

/opt/firefox/firefox report.html

it launches it fines but the program waits for me to close the window or kill the script. I want to leave the window open and finish the script since it proceeds to do a clean up. how do i do that. background the process?

nohup program arguments &
