I just wanted to share this site; it's a fantastic resource for two reasons — the content is excellent (concise and practical) and the delivery (website UI/navigation) makes it so, so simple to peruse. Seriously. Check out this page from the beginner section for example: https://linuxjourney.com/lesson/stdout-standard-out-redirect
The terminal commands are easy to understand, and you can learn how to use these simple commands in under a minute. It's been a hell of a lot better than googling for books, reading forums and whatever else for me so far. Maybe this is a commonly reposted site; if so, my bad. If not, enjoy.
