Nu Shell Is Cool

I had a csv file with data that looked like this. And I needed to convert the date field into this: I tried to do this with awk first because it seemed like it would be a good fit. I'm sure it's possible but the syntax is obscure and I couldn't figure it out. I ended up with something like this (not working): When I can't get something in a single for loop or a few pipes I'll reach for a general purpose programming language. So I fired up iPython and wrote this to convert the file. This works but it was more verbose than I wanted. I'm sure there's other ways to do it, but it felt like something I should be able to do in my shell. Finally, I tried it with nu: It was a more elegant and readable solution. I'm very impressed with how far nu has come and thankful for their helpful community who helped me quickly figure this out.
