This guide is a followup to An Illustrated Guide to Shell Magic: Standard I/O & Redirection. It's about some of the other ways that Bash and its relatives provide for composable tools and general problem-solving.

It's far from comprehensive. Rather, it's a survey of some techniques and ideas that will let you spend less time typing and more time just doing stuff on a Raspberry Pi or similar machine.

We'll touch on documentation, software installation, persistent terminal sessions, keybindings, pattern matching, process monitoring, aliases, basic scripting, and more.
