RE: RE: RE: RE: Making a Hash of Arrays

except, when I try and print the returned hash:

 my %first_hash = processfile($file2, $list2);
   
    foreach my $k (sort keys %first_hash){
print "$k\n$first_hash{$k}\n";   
 }
[download]

it returns:

MonName
ARRAY(0xcb420)
SrcRtr
ARRAY(0xcb468)
ifSpeed
ARRAY(0xcb444)
[download]

rather than the value of the keys.

That's because they're REFERENCES to arrays. You need to dereference them (`@{ $array_ref }`). `$_="goto+F.print+chop;\n=yhpaj";F1:eval`	[reply]

So you need to dereference the arrays. @$arrayref. If you just need to know what's in the hash, use Data::Dumper. It does a great job of expanding references and can be made to do all sorts of pretty printing. `use Data::Dumper; print Data::Dumper->Dump([\%yourhash], ["name of your hash"]), "\n";` [download] You can also use that to print your arrays and such.
