Hello all, I have a seemingly simple question, but I fear it entails some underlying complexity. I need a program (using perl and curses) to run under at and take absolute priority on a users terminal at a specified time (the user will be logged in with ssh and may be logged into another computer via minicom or kermit). Now I know job control (nice, renice, bg, fg, etc) but this app must take absolute priority over what they are doing and be interactive on their terminal. Am I safe messing around with priorities and/ or suspending the user's jobs during the duration of my program or is there a better approach to this? Thanks for taking the time to read my post.
