如何在JSON文件中用空字符串替换匹配字符串?

Question

我有一个文件，其中每行是一个JSON对象:

{"index":{}}
{"msg_text":"yes","@timestamp":"2019-03-31T00:01:59.574Z","o_error":"INTERNAL_INVALID_MESSAGE","sender":"353830465174","account_id":"e15965cf-ffc1-40ae-94c4-b450ab190222","recipient":"49223","@version":1,"submission_ts":1553990519574000,"delivery_ts":1553990519574000}
{"index":{}}
{"msg_text":"yes","@timestamp":"2019-03-31T00:01:59.574Z","o_error":"INTERNAL_INVALID_MESSAGE","sender":"353830478555","account_id":"e15965cf-ffc1-40ae-94c4-b450ab190222","recipient":"49223","@version":1,"submission_ts":1553990519574000,"delivery_ts":1553990519575000}
{"index":{}}

我想删除所有的delivery_ts字段和值。下面就是我想要的:

{"index":{}}
{"msg_text":"yes","@timestamp":"2019-03-31T00:01:59.574Z","o_error":"INTERNAL_INVALID_MESSAGE","sender":"353830465174","account_id":"e15965cf-ffc1-40ae-94c4-b450ab190222","recipient":"49223","@version":1,"submission_ts":1553990519574000}
{"index":{}}
{"msg_text":"yes","@timestamp":"2019-03-31T00:01:59.574Z","o_error":"INTERNAL_INVALID_MESSAGE","sender":"353830478555","account_id":"e15965cf-ffc1-40ae-94c4-b450ab190222","recipient":"49223","@version":1,"submission_ts":1553990519574000}
{"index":{}}

如何使用Linux命令执行此操作?

编辑JSON是jq存在的目的。

jq -c 'del(.delivery_ts)' <in.json >out.json
