bash - 如何在 select 和 test 函数中传递参数？

Question

我有从 qbittorrent 中提取的 JSON 数据:

  }

所以我想匹配名称中有一些文本的所有数据，所以，在 Bash 中我写了这个，但我不能让它工作。

一些声明开始，实际上我通过参数传递数据，所以我使用$1:

TXTIWANT="test"
MYJSONDATA= Here I put my JSON data

那么这个对我不起作用的jq方程是这样的:

RESULTS=$(echo "$MYJSONDATA" | jq --raw-output --arg TOSEARCH "$TXTIWANT" '.[] | select(.name|test("$TOSEARCH.";"i")) .name')

但我总是得到错误或所有数据，我想是因为 $TOSEARCH 没有展开。

也许有更好的方法来搜索值内的字符串？

我做错了什么？

Answer 1

使用 jq 进行变量(或过滤器)插值的正确语法如下所示:

"foo \(filter_or_var) bar"

在你的情况下:

jq --raw-output --arg TOSEARCH "$TXTIWANT" '.[]select(.name|test("\($TOSEARCH).";"i")) .name')
