Namaste, my illustrious List leaders and senior members, I had already asked my question here: https://lists.debian.org/debian-user/2021/06/msg00423.html
But i guess that owing to my continuing with a SOLVED thread i wasn't able to draw attention. Please post your replies on the above thread. I shall post a summary here while acknowledging your comments and mark it solved. I asked the question to restrict making multiple forks and reduce memory/processor load. The screensaver code here: https://lists.debian.org/debian-user/2021/06/msg00309.html be saved as ssvr.sh executable. Best. Rajib Etc.
