我有一个JSON文件:
{
"header": {
"uuid": "c578592a-a751-4993-9060-53f488597e59",
"timestamp": 1522938800,
"productionDateTime": "2018-04-05T14:33:20.000+00:00",
"producers": {
"operator": null,
"application": {
"com.example": {
"id": {
"string": "1"
},
"name": {
"string": "Test"
}
}
},
"station": null,
"equipment": null,
"partner": null,
"flow": null
},
"correlationContext": {
"array": [{
"correlationId": "98440498-3104-479e-9c99-f4449ba8f4b6",
"correlationDateTime": {
"string": "2018-04-05T14:30:39.000+00:00"
}
}]
}
},
}
我想创建n个文件来复制JSON文件,但是使用随机的correlationId和correlationDateTime。
您有任何提示或建议吗?非常感谢提前!

使用jq
并将适当的随机值生成作为读者的练习:
$ jq --arg cid "foo" --arg cdt "bar" '
.header.correlationContext.array[0]={
correlationId: $cid,
correlationDateTime: {string: $cdt}
}' tmp.json

在这里: -
#!/bin/bash
alias uid="python -c 'import sys,uuid; sys.stdout.write(uuid.uuid4().hex)' | pbcopy && pbpaste && echo"
dt=$(date "+%Y%m%d-%H%M%S")
# For above two values I am leaving with you. If you have best option please go for it
i=0
while [ $i -le 20 ]
do
sed "/correlationId/s/98440498-3104-479e-9c99-f4449ba8f4b6/"$uid"/;s/2018-04-05T14:30:39.000+00:00/"$dt"/" yourJsonFile.json > testcase$i.json
i=$((i+1))
done
