This set of examples goes with zine Bite Size Bash. There's approximately one file per page of the zine.

To run the globs example, run:

bash 12-globs.sh

I'd recommend both opening the example file in a text editor (so you can read the code) and running the example in a terminal (to see the output).

If you're confused about something in one of the examples, experiment! Make your own examples! See what happens! I've learned a LOT about bash by just experimenting with different tiny shell scripts and making sure I understand what they're doing.
