问题 This question already has answers here : jq: pass string argument without quotes (3 answers) Closed 2 years ago . How do I pass a variable argument to JQ program that will be used as a filter. Since by default --arg passes the argument as a a string wrapped with quotes the same cannot be used to apply a filter. here is the JQ program that finds a particular path in the given json and adds a static key value to that path but doesn't work because of the quotes issue. --argjson name '{ "pattern"

问题 I want to transform JSON file into bash array of strings that i will later be able to iterate over. My JSON structure is as follows: [ { "USERID": "TMCCP", "CREATED_DATE": "31/01/2020 17:52" }, { "USERID": "TMCCP", "CREATED_DATE": "31/01/2020 17:52" } ] And this is my bash script: test_cases=($(jq -c '.[]' data.json)) echo ${test_cases[0]} echo ${test_cases[1]} echo ${test_cases[2]} echo ${test_cases[3]} As you can see it returns array with 4 elements instead of 2. Output: {"USERID":"TMCCP",
