# There's another process you want to wait on.  In this example,
# you know the pid, and it's contained in the file $PID_FILE.
while ps -p `cat $PID_FILE` > /dev/null; do sleep 1; done

# Now you can continue knowing that process has finished...

If the process is a child of the current shell, just use wait $pid Otherwise, use kill -0 $pid >/dev/null.
Controlling complexity is the essence of computer programming.
