I spent a couple of hours trying to manipulate strings using zsh, awk, sed, cut, regex and grep. Two hours of hair pulling frustration Finding things that would work at the command line wouldn’t work when executed in a script. Remembered that I was a proficient python programmer a year ago. 10 minutes later, I’d written and tested a 4 line python script that did everything I needed across a set of test data. The CLI is liberating and powerful, but sometimes it’s just an absolute pain in the arse.
