如何过滤嵌套数组中不包含键值对的条目
How can I filter for entries that do NOT contain a key-value pair within a nested array
假设我有以下 JSON 输出:
{
"Stacks": [
{
"StackName": "hello-world",
"Tags": [
{
"Key": "environment",
"Value": "sandbox"
},
{
"Key": "Joe Shmo",
"Value": "Dev"
}
]
},
{
"StackName": "hello-man",
"Tags": [
{
"Key": "environment",
"Value": "live"
},
{
"Key": "Tandy",
"Value": "Dev"
}
]
}
]
}
我将如何编写一个 jq
查询来获取所有 StackName
的堆栈 NOT 具有 Tags
值 "Key": "Joe Shmo"
?所以结果 return 只是 hello-man
.
使用 contains
,像这样:
jq -r '.Stacks[]|select(.Tags|contains([{"Key": "Joe Shmo"}])|not).StackName'
注意:-r
从输出中删除引号,否则 jq
将打印 "hello-man"
(在双引号内)
.Stacks[]
| select( any(.Tags[]; .Key == "Joe Shmo" ) | not)
| .StackName
这会有效地检查是否相等(any
具有短路语义),而 contains
会检查是否包含。
