Working with Linux

Info

If we want to refine our search even more and only print the first element in the dataIds object of therequest body, use the following:jq 'select(.requestBody.dataIds[0] != null) | .requestBody.dataIds[0]'access.log
We can even perform arithmetic operations with the returned value, such as incrementing it:jq 'select(.requestBody.dataIds[0] != null) | .requestBody.dataIds[0] + 1'access.log
