I’m a dev with 20yoe in mostly Java and js but have various amounts of experience with other languages. I’ve decided that I need Perl in my toolkit because I find it on even the most minimal boxes preinstalled and I can’t always install Java or Js just to do admin things. Typically I use bash for these tasks but I just need a little more ability to abstract than what bash easily provides. What would you all recommend as the place to start? Most guides that I run into assume that I’m a beginner to programming and it feels slow. My normal method of learning a new language is to stumble through building a web server but I’m not sure that the way to go here.

I am working with the IP::Geolocation::MMDB module which replaces the deprecated modules for GeoIP databases.
I am having trouble understanding how to extract data.
my $ip = "8.8.8.8"; my $db = IP::Geolocation::MMDB->new(file => "$geolitecitydb"); my $geodata = $db->record_for_address($ip); print Dumper($geodata); Using Data::Dumper as above to show the results, I see something like (truncated):
Dumper...........$VAR1 = { 'continent' => { 'geoname_id' => 6255149, 'names' => { 'de' => 'Nordamerika', 'es' => "Norteam\x{e9}rica", 'zh-CN' => "\x{5317}\x{7f8e}\x{6d32}", 'ru' => "\x{421}\x{435}\x{432}\x{435}\x{440}\x{43d}\x{430}\x{44f} \x{410}\x{43c}\x{435}\x{440}\x{438}\x{43a}\x{430}", 'fr' => "Am\x{e9}rique du Nord", 'ja' => "\x{5317}\x{30a2}\x{30e1}\x{30ea}\x{30ab}", 'en' => 'North America', 'pt-BR' => "Am\x{e9}rica do Norte" }, 'code' => 'NA' Supposing I just want to grab the value of continent=>names=>en portion (value: 'North America') and write it to a value -- how would I do this? I'm having problems understanding the documentation I'm reading to deal with hashes of hashes.
Most examples I can find online involve looping through all of this; but in my case, I just want to make $somevar = 'North America.' I'd like to repeat it for other data as well, which is returned in this hash.
It feels like something like:
$geodata{city=>names=>en} should work, but it doesn't.

I have been using version 5.22.1 for years, and it did what I needed to do. After all these years, I need some additional functionality, so I thought installing the latest might help.
Which is when I found that ActiveState has changed the installation process totally. Anyway, I went through the installation of the "recommended" version, and installation seemed to go fine.
I then ran the following simple code through both versions.
use HTTP::Tiny; my $url ='https://www.scrapingcourse.com/ecommerce/' ; my $response = HTTP::Tiny->new->get($url); print $response->{content}; Version 5.22.1 runs this fine and gives me the HTML of the page.
Version 5.36.3 gives me the following errors;
IO::Socket::SSL 1.42 must be installed for https support
Net::SSLeay 1.49 must be installed for https support
When I use the old ppm command for Version 5.22.1, it gives me a list of 271 packages installed.
When I used the new "state" command: "state packages", it showed nothing.
So I used "state" to "install" IO-Socket-SSL, and Net-SSLeay, and now those are the only two that show up in the "state packages" list.
But it did not change functionality. The error messages are still there, and no execution.
It doesn't complain about HTTP::Tiny.
I tried installing Strawberry. But it had a problem with a more complex part of my original project, so I went back to ActiveState 5.22.1, which works fine.
Anybody got any ideas about what I need to do to get 5.36.3 actually working?
