现在，我想将的值更改.seasons | .[] | select(.seasonNumber==2).monitored为 false。我可以使用以下命令来实现：
# '.[] | select(.title==$TITLE)' is used to get example output
# '--argjson SEASON "$((season-1))"' will be 2 in this case (giving 3rd object, which is indeed season 2)
[api request] | jq -rM --arg TITLE "${info[$((series-1))]}" --arg SEASON "$((season-1))" '.[] | select(.title==$TITLE).seasons | .[] | select(.seasonNumber==$SEASON) | .monitored = false'
{
"seasonNumber": 2,
"monitored": false,
"statistics": {
"previousAiring": "2016-05-25T00:00:00Z",
"episodeFileCount": 0,
"episodeCount": 0,
"totalEpisodeCount": 23,
"sizeOnDisk": 0,
"percentOfEpisodes": 0
}
}
但是，我不想要这个输出。我现在只得到对象本身。我想要完整的示例输出，以及更改的值。我认为问题出在后面|，.seasons但我不知道如何修复它。
我的目标是示例输出，但监控更改为false（并且只针对我想要的季节）
编辑：应该提到我想直接正确地在终端中获取输出。因此不要在过程结束时或过程中保存到文件中（然后在新命令中使用它）。但是多个命令和变量是可以的。
回答穆鲁的问题：
#for simplicity I changed to values of the --arg's to actual value's
jq --arg TITLE "The Flash (2014)" --arg SEASON "2" '.[] | select(.title==$TITLE).seasons[] |= (select(.seasonNumber==$SEASON) |= (.monitored = false))'
首先它输出的[api request]是[api request] | jq -rM --arg TITLE "The Flash (2014)" '.[] | select(.title==$TITLE)'
其次，它...不会改变值。忽略完整的 api 输出而不是仅忽略示例输出，它仍然"monitored": true,显示"seasonNumber": 2,。
编辑2：
我让它工作了：
jq --arg TITLE "The Flash (2014)" --argjson SEASON "4" '.[] | select(.title==$TITLE) | .seasons[] |= (select(.seasonNumber==$SEASON) |= (.monitored = false))'
区别：
select(.title==$TITLE).seasons[]->select(.title==$TITLE) | .seasons[]--arg SEASON "4"->--argjson SEASON "4"
答案1
您想要的是本质上两个更新（更新匹配的季节对象，然后用该对象更新季节数组）。所以：
.[] | select(.title==$TITLE).seasons[] |= (select(.seasonNumber==$SEASON) |= (.monitored = false))
这里，内部更新（|=）更新select输入数组中的 ed 季节，外部|=使用结果更新数组。
