I've had RegexBuddy installed on my computer for so long. It's been part of my basic dev setup for years: https://www.regexbuddy.com/

I used to use it a lot, although I've not used it in quite a while. I don't recall the last time I even needed to write a regex. Somehow it's still stuck in my head.

Well worth having it if you want a tool to hack around large blocks of text and play with regex in a "live" environment.

$40 is a bit steep, but I'd probably be willing to pay for a Linux version.
