The Perl and Raku Conference 2023 in Toronto

Starting with the bare basics of command-line pipes and redirection, I further cover the standard "Unix filter" form of code, and the benefits of nudging old code into this form.

These techniques are my bread-and-butter for exploratory programming and data analysis, and include a few of my best tricks.

Slides will cover variants for (Raku|Perl|Python) and (Mac|Windows|Unix).

Filters are the basic tools of command-line data munging. grep head cut sort uniq wc diff, pipes + redirects, intro + advanced tips. Why stop there? *You* can write your *own*. Perl, Raku, & Python have strong support for writing filters. Existing code often works better when refactored as a filter.
