I thought this lab was really cool. From Unit 1 it felt different because I was working with using commands such as cat and using the straight line which was totally different from before. The codes from Unit 1 compared to Unit 2 look completely different and more intimadating. In terms of learning, this kind of thinking felt fimiliar becuase I took computing courses that lookk familiar. The way I used terminal felt so different compared to Unit 1 because for Unit 1 it seemed to be more straight torward whereas so far in Unit 2 it has all these other commands seperated with the '|' symbol. Working on this lab made me realize how cool it was to use code to find specific words with specific requirments rather than looking one at a time. I got stuck on the last 3 problems of the exercise and what I did to get unstuck is I messaged one of the students and asked for help. I have just now started getting help from my peers because I have some in my in-person classes so it makes it easier to comunication about the lessons.
