The latest computing hack was how to see the contents of secrets in Kuberenetes but that's boring so let me tell you another one! I've been writing some bash scripts lately and learned some new commands that I didn't know about.
Use sponge if you want to directly modify a json file with jq. jq doesn't have a -i option like sed. Also use trap to clean up the mess when your script exits.
I feel this sounds boring too!
