Relearning SED

I needed to use sed to alter the gCode files each time I remade them.  I had forgotten so much from when I wrote Unix shell scripts every day, but like riding a bike without a seat, once you learn it, it comes back.


  1. "Some people, when faced with a Unix problem, think 'aha, I know, I'll use sed(1)!

    Now they have two problems."

  2. Actually sed solved my problem pretty painlessly.
