Hi, Thanks for the reply guys. From the sounds of it, there is no "simple" way of doing this. I think the approach I'm gonna take is putting some examples in "comments" inside the script, so they can test the different paths themselves (and if needed, as their host). So something like:

my $path = 'apachectl';

my $output = `$path -v`;
my @split = split /:/, $output;

if ($split[1] !~ /\d\.\d\.\d/) {
  print qq|Cant find Apache version <br />|;  
} else {
  print qq|$split[1] <br />|;
}
