Here are a series of warm-ups and drills for various batch renaming tasks. Ideally, you will try these out on the command line, but you're also welcome to explore other automated ways to get these tasks done.
In warm-ups, you'll find two tasks that will ready you for the refoldering drills. Stay the course, do not panic, consult some handy guides, and remember to make lots of mistakes along the way.
./reset.sh should reset the files to their original state.
Submit an issue if there is something amiss with the testing files. Sometimes, this prompts the creation of additional exercises!
