Updates to Chapter 13, “Directory Operations”

[This post notes differences between the fifth and sixth editions.]

Our updates to Chapter 13 aren’t that exciting. There’s not much that has changed in the world of Perl and directories. It’s almost dull, even.

  • Use variables as directory handles: opendir my $dir, $directory.
  • Mention a couple more modules incidental to some of the examples, including File::Spec::Functions, Path::Class, and File::Temp
  • Show a find2perl example. We mentioned File::Find only to say that we weren’t going to say anything about it. Also mention the improved interfaces of File::Finder and File::Find::Rule
