Re: Managing the fork/execing and reaping of child processes

Are you sure that your exec call worked? It can be tricky, see the docs exec.

You could check if it fails :-

exec ('foo') or die "couldn't exec foo: $!";

I added the ".. or die 'couldnt..'" but it doesn't get invoked. It seems to me that, in this case, exec (unlike fork) would either always work, or never work. The presence of "Hellos" in the output indicates to me that it's working.	[reply]
