Description:

I have a program that forks and runs another executable. In the meanwhile, the main program runs some diagnostics, and should terminate when the child does. How can I do this?

Trap SIGCHLD.

And of course the way you would do this is by...

sub catch { my $signal_name = shift ; die "Caught CHLD" ; # or whatever you wish to do! } $SIG{CHLD} = \&catch;

See http://perldoc.perl.org/ and search on PERLIPC

Good Luck!,
