本文介绍了jq:json对象的输出数组的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
说我有输入:
{
"name": "John",
"email": "john@company.com"
}
{
"name": "Brad",
"email": "brad@company.com"
}
如何获取输出:
[
{
"name": "John",
"email": "john@company.com"
},
{
"name": "Brad",
"email": "brad@company.com"
}
]
我都尝试过
jq '[. | {name, email}]'
和
jq '. | [{name, email}]'
这两个都给了我输出
[
{
"name": "John",
"email": "john@company.com"
}
]
[
{
"name": "Brad",
"email": "brad@company.com"
}
]
在文档中，我也没有看到数组输出的任何选项，感谢任何帮助
I also saw no options for an array output in the documentations, any help appreciated
推荐答案
使用slurp模式:
o --slurp/-s:
Instead of running the filter for each JSON object
in the input, read the entire input stream into a large
array and run the filter just once.
$ jq -s '.' < tmp.json
[
{
"name": "John",
"email": "john@company.com"
},
{
"name": "Brad",
"email": "brad@company.com"
}
]
