我有多个s3清单文件,每个文件对应于给定日期范围的日期。我希望合并所有清单文件以生成单个清单文件,从而允许我执行单个Redshift副本。
清单文件1:
{
"entries": [
{
"url": "DFA/20161001/394007-OMD-Coles/dcm_account394007_activity_20160930_20161001_050403_294198927.csv.gz"
}
]
}
清单文件2:
{
"entries": [
{
"url": "DFA/20161002/394007-OMD-Coles/dcm_account394007_activity_20161001_20161002_054043_294865863.csv.gz"
}
]
}
我正在寻找输出: -
{
"entries": [
{
"url": "DFA/20161001/394007-OMD-Coles/dcm_account394007_activity_20160930_20161001_050403_294198927.csv.gz"
},
{
"url": "DFA/20161002/394007-OMD-Coles/dcm_account394007_activity_20161001_20161002_054043_294865863.csv.gz"
}
]
}
我确实尝试了
jq -s '.[]' "manifest_file1.json" "manifest_file2.json"
以及Stackoverflow中发布的其他建议但无法使其正常工作。

或者,不依靠reduce
:
$ jq -n '{entries: [inputs.entries[]]}' manifest_file_{1,2}.json
{
"entries": [
{
"url": "DFA/20161001/394007-OMD-Coles/dcm_account394007_activity_20160930_20161001_050403_294198927.csv.gz"
},
{
"url": "DFA/20161002/394007-OMD-Coles/dcm_account394007_activity_20161001_20161002_054043_294865863.csv.gz"
}
]
}
请注意,inputs
是在jq 1.5版中引入的。如果您的jq没有inputs
,则可以使用jq -s
,如下所示:
$ jq -s '{entries: [.[].entries[]]}' manifest_file_{1,2}.json
答案 1 :(得分:0)
所以如果通过"合并"你的意思是通过连接它们将"entries"
数组组合成一个数组,你可以这样做:
$ jq 'reduce inputs as $i (.; .entries += $i.entries)' manifest_file{1,2}.json
哪个收益率:
{
"entries": [
{
"url": "DFA/20161001/394007-OMD-Coles/dcm_account394007_activity_20160930_20161001_050403_294198927.csv.gz"
},
{
"url": "DFA/20161002/394007-OMD-Coles/dcm_account394007_activity_20161001_20161002_054043_294865863.csv.gz"
}
]
}
