A good suggestion, but it's begging for some decoupling. 
sub grepfile {
    my ($rx, $file) = @_;

    my $ret = system(
        qw/ perl -0777 /,
        -e => q{$a = shift; exit (<> !~ /$a/)},
        $rx, $file
    );
    return $ret == 0 if $ret != -1;

    require Carp;
    Carp::croak "Failed invoking perl for grepfile(): $!";
}

Note how using system(LIST) eliminates any quoting headaches in one easy step.
