[英]Using jq how can I replace the name of a key with something else
This should be easy enough... I want to rename a few keys (ideally with jq), whatever I do seems to error though.这应该很容易...我想重命名几个键(最好用 jq),但无论我做什么似乎都会出错。 Here is a json example below:
下面是一个 json 示例:
[
{
"fruit": "strawberry",
"veg": "apple",
"worker": "gardener"
}
]
I'd like to rename the veg key to fruit2 (or example, whatever is easiest) and also the worker key to job.我想将 veg 键重命名为fruit2(或例如,任何最简单的)以及工作的工人键。
I realize this is possible in sed, but I'm trying to get to grips with jq我意识到这在 sed 中是可能的,但我正在努力掌握 jq
Use the following jq approach:使用以下jq方法:
jq '[.[] | .["fruit2"] = .veg | .["job"] = .worker | del(.veg, .worker)]' file
The output:输出:
[
{
"fruit": "strawberry",
"fruit2": "apple",
"job": "gardener"
}
]
The key (:-) is with_entries.关键 (:-) 是 with_entries。 Eg, given a single object:
例如,给定一个对象:
with_entries(if .key == "veg" then .key = "fruit2" else . end)
In your case, since you have an array of objects, you could wrap the above in map( ... )
.在您的情况下,由于您有一个对象数组,您可以将上述内容包装在
map( ... )
。
