linux下格式化json

有时候有一个json的字符串不容易清晰的查看 例如：

[root@aliyun ~]# cat a {"openid":"o-U6bs4yPp1pQB1eTdbXxuFp4v5Y","nickname":"郭新鹏","sex":1,"language":"en","city":"海淀","province":"北京","country":"中国","headimgurl":"http:\/\/wx.qlogo.cn\/mmopen\/DU8c6WuxXjdzqOliauibrW0Qz3fKa1pj8vFyfNFvrUPial0IVFBC6XzNUKkPTG71aNjDqjb4ZIHHQ0wicGmw8bvhwY7ebKePEicnE\/0","privilege":[],"unionid":"o1GCawQURlBzS_wHVheBxNwp2IFk"} [root@aliyun ~]# cat a | jq . { "openid": "o-U6bs4yPp1pQB1eTdbXxuFp4v5Y", "nickname": "郭新鹏", "sex": 1, "language": "en", "city": "海淀", "province": "北京", "country": "中国", "headimgurl": "http://wx.qlogo.cn/mmopen/DU8c6WuxXjdzqOliauibrW0Qz3fKa1pj8vFyfNFvrUPial0IVFBC6XzNUKkPTG71aNjDqjb4ZIHHQ0wicGmw8bvhwY7ebKePEicnE/0", "privilege": [], "unionid": "o1GCawQURlBzS_wHVheBxNwp2IFk" }

安装jq即可

yum install jq
