in reply to print a hash ref

$cacheDBs{$db}{mxs} is a hash reference. If you want to print its keys and values, do so: 
for my $key (keys %cacheDBs) {
    my $mxs = join ':', map "$_ $cacheDBs{$db}{mxs}{$_}", keys %{ $cac
+heDBs{$db}{mxs} };
    print "\n/opt/freeware/bin/gmetric -n $db -T $db -g $Ggroup -t dou
+ble -u MaxSize -v $mxs -d 45)\n";
}

Untested (the code was not runnable to demonstrate the issue).

    ok thank you! it ran to completion, however I dont want the GB or MB printed which is why I put it as a value: any way I can only print the 1.0 in mxs and not the GB? I still need the letters GB/MB but cannot have them in the gmetric CLI. maybe use an array to store GB/MB? 
    '/cache-m/usr/cachesys/mgr/' => {
                                            'free' => '91.7',
                                            'sz' => '1.0',
                                            'mxs' => {
                                                       '1.0' => 'GB'
                                                     },
                                            'dfree' => '2.2',
                                            'avail' => '917'

      Not a nice way, but if it's only for printing, treat it like a number, e.g. add 0 to it and print the result.


      I'm too lazy to be proud of being impatient.
