JQ 结合 json 与键：值

Question

I have two Json files

First:

''' { "KeyID": 7532173, "KeyDetails": "Level 12" } '''

Second: ''' { "KeyID": 7532173, "Level": "Access Level" } '''

I would like to combine them matching the key:value pair of KeyId

Please advise on how to proceed

Answer 1

You could use if... then... else... end , or more briefly, select :

jq -s 'select(.[0].KeyID==.[1].KeyID) | add' file1.json file2.json
