I'd like to fork several child processes and read lines from each, for example:
open my $fh_foo, '-|', 'yes', 'foo' or die $!;
open my $fh_bar, '-|', 'yes', 'bar' or die $!;
while (<$fh_foo> OR <$fh_bar>) { # magic happens here
say "got a line from one of them: $_";
}
Is there a CPAN module or well-known recipe that can provide the necessary
magic to poll both filehandles and read a line from either?
If not, I will write something using select() and sysread(), but I wondered
if there was some more convenient way to do it.
