                     15: while a  background process is being  executed.  The shell prints

                     19: The command  wait tells the shell to  suspend execution until the
                     20: child  process with  the given  pid is completed.   If no  pid is
                     21: given, wait suspends execution until all background processes are
                     22: completed.   If the  process with  the given pid  is not  a child
                     23: process of the current shell, wait returns immediately.

                     25: The shell executes wait directly.
