Quick practice exercise with sed

Problem Solution Coda Recap. Problem As I try to get my blog up and running using the new Hugo/blogdown framework, I find myself needing to reformat a bunch of dates in the yaml front matter from mm/dd/yyyy to yyyy-mm-dd for all of the .Rmd files in a directory. For this I’m going to use sed, something I’ve been meaning to get more practice with. I’m going to try to come up with the syntax before consulting google, and then see how close I was.
