For me, a mixture of Bash and Perl sometimes makes sense when writing a quick proof of concept. If the main part of the code works out, i can always go to CPAN, find a module that fits my need, read the docs and then implement it.

But for a first try, it's often quicker to just calling wget than it is to install and use LWP::UserAgent. And for a PoC, it really doesn't matter if bash calls wget and then the perl script, or if the perl script calls wget when needed. It's just throw-away code anyway.

Case in point: Perl+PostgreSQL+GeoIP = Awesome! was my proof of concept, which then turned into GeoIP revisited. The proof of concept was ugly and was using external (command line) tools. But it quickly showed me what worked and what didn't. And it was "good enough" to post on PM to get some feedback from which i learned that i was using a deprecated GeoIP database version. Which then lead to a "Pure Perl" version that was nicer, but also more time intensive to implement.

perl -e 'use Crypt::Digest::SHA256 qw[sha256_hex]; print substr(sha256_hex("the Answer To Life, The Universe And Everything"), 6, 2), "\n";'
