I've been a full-time #linux user for about 18 months now. First #ubuntu, then #mint, now #fedora (yes, it is very likely mastodon's fault). Very happy with it all. And I have learnt plenty. Seeking #recommendations for (e)books or courses for learning how to terminal/bash better. If it's free (or low cost) that'd be cool, because money is pretty tight right now.
I'm not a complete beginner, but sed and parameter expansion and regex-looking things are intimidating.
boosts welcome, I suppose.
