That’s also what I’m doing! It’s great to jump back in, and learning new things! Hope you have a great time doing it! Yes! I’m looking forward to understanding it better! It’s so different to have to learn to use the command programs I use, for example. I feel GUIs make the user able to use a program sufficiently very fast, but this way hide the way it functions. Reading man pages and looking at the output of the --help flag can be considered tedious, but I feel it allows me to understand the program better, and use it in a more flexible way. I guess what I’m trying to say is that the programs I’m used to usually very strictly tell you (through visual cues, etc), and these command line tools do not, or are at least much less strict. And I like that, it’s refreshing!
