Working with JSON Using JQ ​

Use jq to manipulate JSON on the command line.

Check if JSON is empty ​

To check if a JSON file or object is empty, pipe it to jq . == {}

Example: Check if POST request returns an empty body

IS_EMPTY=$(curl -X POST <url> | jq ". == {}")
echo $IS_EMPTY

IS_EMPTY=$(curl -X POST <url> | jq ". == {}")
echo $IS_EMPTY
