Author here. I don't know if we'll be writing shell scripts in five years for our jobs, but I do know that spending a few minutes writing sed makes me feel connected to my tribe of linuxy people with a love of unix history.
I also know that thinking about pattern matching is fun, it's a little puzzle solved with a skillset that transfers to other cli tools.
Post also opens with a classic interview question I've used for years: no ls on the box, five ways to list the directory tree you're in. A handful of answers at the bottom :)
