Re: open pipe for input and die

Why not use the fact that a pipe-open returns the PID of the child on success?

my $child = open my $y, '/usr/bin/sleep 5|'
    or die "Couldn't spawn: $!/$?";
END {
    kill 9, $child
        if $child;
};

Thanks. I didn't realize `open` will also return the pid, thus i used `open2`. The rest of the solution is the same though. I have a `__DIE__` handler instead of an `END` block, because the program itself forks later on and I turn the handler off in the child.	[reply] [d/l] [select]
