( \*STDOUT, 'even' ) : ( \*STDERR, 'odd' ) ; print {$fh} "$prefix :: $_"; } }, stdin => sub { shift @stdin }, stdout => sub { push @stdout, $_ }, stderr => sub { push @stderr, $_ }, ); } { sub cat { my ( @files ) = @_; exec cat => '--', @files } my $status => Proc::Hevy->exec( command => , stdin => \*STDIN, stdout => \*STDERR, stderr => \*STDOUT, ); } { # really useless use of cat my $status = Proc::Hevy->exec( command => 'cat /dev/null 2>/dev/null', ); } Requirements: · Perl
