   If you own the other process (or you're root) you can use signal 0 to
   verify that it's still alive:

     me% sleep 60 &
     [1] 10175

     me% kill -0 10175                          [$? = 0]

     me% kill -0 10176
     kill: kill 10176 failed: no such process   [$? = 1 or 2]

   Try this:

     pid=5543  # or $1 or whatever
     while kill -0 $pid 2> /dev/null; do
         sleep 60
     done
     /path/to/newjob.sh
