.... and you should probably unbuffer STDOUT as well. Put this line $| = 1; before the rest of the code, and include a newline in your output: > > #!/usr/bin/perl $| = 1; > > my $email = <>; > > chomp($email); print "1\n"; In fact, now that I think about it, the missing newline in your output is VERY probably the reason POE never saw anything... remember the "Filter" parameter, above? That's what POE uses to know when a complete block of input/output has happened with the child process. HTH! L8r, Rob
