OMG, what's that? What's wrong with prog1;prog2 or prog1 && prog2

@zolden, Suppose prog1 is already running and you need prog2 to start after prog1 exits. However, there is a simpler way to do what the submitter has proposed: while pkill -0 prog1; do sleep 10; done; prog2

@daa, yes you're right. But i 've just found another simpler : press Ctrl+Z to suspend prog1 then : fg && prog2

Nevertheless if you don't have hand on prog1, it's a good means to wait.
