The Perl and Raku Conference in Houston

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.

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