Download the whole podcast
==========================

Feeling evil… Assume that there's a podcast with a feed and you want
to download all the episodes. Like a music show, for example.

First, get the feed, saving it as rss.xml because we're going to need
it in the next statement.

    curl -o rss.xml https://musicforprogramming.net/rss.xml

Then, get every enclosure:

    for f in $(perl -ne '/<enclosure url="(.*?)"/ && print "$1\n"' rss.xml); do
      curl --continue-at - --remote-name "$f"
    done

The --continue-at - option should make it possible to resume
downloads at a later stage. curl will skip all the bytes already
downloaded, effectively skipping the download. That's what I'm hoping
for, in any case.

The --remote-name option saves the episode under its remote name.
This is what most people would expect, I think.

You know how it goes, though: never parse HTML (or XML) using regular
expressions. I'm doing it here and it is definitely a bad idea!

I'm also too lazy to install a real XML parser and doing the real
thing, so it is what it is.

@takeonrules@dice.camp wrote in to say that as someone "who doesn't
use Perl" the have a solution using Ripgrep and xargs. I like it very
much and feel like I should be using rg and xargs more often.

    rg "<enclosure url=['\"]([^'\"]+)['\"]" rss.xml -r '$1' --only-matching \
      | xargs curl --continue-at - --remote-name
