If you want the exit status of the child process, add `wait $!'
Thanks for this information.
Is there a need then to point the aspect out that exit values can be determined
for child processes even if they terminated before a wait command would be
performed?
Is this what you mean? If you have the pid of an asynchronous command --
and the easiest way to get that pid is by referencing $! after it was
started -- you can call `wait' with that pid to retrieve the status, even
if it's already terminated.
