What we have is the sequence
1. open MAIL pass
2. print MAIL ????
3. close MAIL fail
step (1) succeeds, step (3) fails. The natural question is did step (2) fail or succeed? I've never seen close on a pipe fail, but it does in this case. I've never seen a print to an open pipe fail either. But, since we are into rare, weird stuff, just curious about the print to the MAIL pipe. print() returns status just like open() or close(). I admit to being stumped. This might tell us something surprising or not - but its easy to do.
print MAIL ...... or warn "print to MAIL failed".
Other way to code:
#!/usr/bin/perl -w
use strict;
my $status = print "this is a test\n";
print "first print returned $status\n";
__END__
output:
this is a test
first print returned 1
