Today I needed to parse some JSON at the command line and do some basic search and replaces and convert it all to CSV. The API call was easy enough with wget, and I was going to use JQ to parse the JSON. But after fiddling with it for 20 minutes and not having much luck, I resorted to my favorites:
Awk, sed, grep, cut. Save API call output to a couple of temp files, parse it with the aforementioned Unix staples in a for loop, And unless time than it would have taken me to properly learn JQ, I had the output and was able to ship it off to my customer.
Sometimes the best tool for the job is the tool you know, love, and trust.
