You touched on it briefly but I'd like to highlight regular expressions in day to day editing and log delving. It's a massive time saver in my experience at least. Coworkers often come to me to help them write a quick regex for something, or to have me double check their work. If you need a playground to get comfortable, https://regex101.com/ https://regex101.com/ is a great resource. Dump some examples you'd like to match and some you don't in the bottom section, and try to write a regex that matches in the top. It will dynamically match as you type, and the right side shows a token by token breakdown of what your regex does.
