https://stedolan.github.io/jq/

下载版本linux版本

jq-linux64

Ubuntu 直接sudo apt-get install jq即可。

2. 解析json

[root@cas script]# cat test.json {"tasks":[{"id":"simpletour-wechat.a17506e7-8204-11e6-a750-da3323f1fcbf","slaveId":"09aef570-d348-47e6-a03b-08c8658d4346-S2","host":"192.168.2.149","startedAt":"2016-09-24T03:12:01.836Z","stagedAt":"2016-09-24T03:11:48.168Z","ports":[31872],"version":"2016-09-24T03:11:47.971Z","ipAddresses":[{"ipAddress":"172.17.0.2","protocol":"IPv4"}],"appId":"/simpletour-wechat"}]}[root@cas script]# cat test.json | jq{  "tasks": [    {      "id": "simpletour-wechat.a17506e7-8204-11e6-a750-da3323f1fcbf",      "slaveId": "09aef570-d348-47e6-a03b-08c8658d4346-S2",      "host": "192.168.2.149",      "startedAt": "2016-09-24T03:12:01.836Z",      "stagedAt": "2016-09-24T03:11:48.168Z",      "ports": [        31872      ],      "version": "2016-09-24T03:11:47.971Z",      "ipAddresses": [        {          "ipAddress": "172.17.0.2",          "protocol": "IPv4"        }      ],      "appId": "/simpletour-wechat"    }  ]}[root@cas script]#

3. 基本用法：

显示key 的value

[root@cas script]# cat test.json | jq ".tasks"

4. 高级用法

[root@cas script]# cat test.json | jq '.tasks[] | {host,ports}'{  "host": "192.168.2.149",  "ports": [    31872  ]}[root@cas script]#
