That's how I learned a lot of things; by literally scanning through everything it had to offer and googling what I didn't understand. I did that for linux utils, language references, most programs I use and most codebases I had to work on. One notable example is the time I had to learn C# 4 years ago. It took an entire morning to scan through the entire language reference and then later I found out I already knew a lot more than "advanced" devs who would just look up stuff as they needed it, without knowing what actually is available in the first place. I feel its the only sensible advice if you want to learn a lot on your own with limited time.
