Re^4: Comparing an array against another array

diff seems to be just what I need, thanks a lot. Is my only option perl5i to use the diff method? Or does anyone know why I'm getting this error? Can't call method "diff" without a package or object reference at backtick.pl line 8.

my $hostname = $ARGV[0];

my @hostFiles = ("filecheck.pl", "hostscript.pl");
my @output =`ssh $hostname "cd Desktop; ls -a"`;

my @diff = @hostFiles->diff(\@output);

`use perl5i::latest;` should do the trick. However, check your install log to see this module installed correctly. I finally had to force install it, due to an error in respect of the `child` method.
