[英]how to use jq to filter an object based on it's key:value pair?
Assuming this is the input假设这是输入
>echo '{"A": {"x": 1}, "B": {"x":2}, "C":{"x":3}}' | jq '.'
{
"A": {
"x": 1
},
"B": {
"x": 2
},
"C": {
"x": 3
}
}
I would like to get the return object of "x" == 2
.我想获得
"x" == 2
的回报 object 。 The only way i know of how to achieve that is thru this我知道如何实现这一点的唯一方法就是通过这个
>echo '{"A": {"x": 1}, "B": {"x":2}, "C":{"x":3}}' | jq '.[] | select(.x==2)'
{
"x": 2
}
Is there a way to have jq return me like this instead?有没有办法让 jq 像这样返回我?
{
"B": {
"x": 2
},
}
with_entries(select(.value.x == 2))
You can also use map_values:您还可以使用 map_values:
map_values(select(.x == 2))
