前言：
事情在工作中被锁定了，我不能在 Excel 中使用 powershell 或任何宏/脚本。我不能将文件带到异地或在个人计算机上使用。我无权访问文件的原始程序。我似乎仅限于批处理脚本。

情况：
我在离线机器上有几百个带有系统信息的 csv 文件，我试图提取第 2 行，然后附加第 3、6 和 20 行的第 4 和第 5 字段。将其导出到新的 . .csv 文件

第一行在后续行中重复，因此我创建了一个函数来识别第 1 行的长度并将其存储在一个变量中以用作后续字符串的偏移量（第 3、6、20 行）。

我将各种行放入变量中，然后将变量回显到文件中。到目前为止，我只关心第 2 行和第 3 行，直到我弄清楚这一点。我要崩溃的地方是我似乎无法将变量用作另一个变量中的偏移量。这总是作为整个字符串出现。
例如：!Ln3:~%L1Len%!

甚至可以按照我尝试的方式做到这一点吗？
是否有另一种方法（在 Windows 批处理中）？

我认为必须有一种方法来使用findstr /C:"Edition ID" dc- .csv* （对于第 6 行）并将该行的其余部分输出到一个变量，但我还没有弄清楚。它也不适用于其他行上的数据，因为这些前导字符的文件中有多个实例。

如果没有，我将只回显行变量，然后手动删除 Excel 中的列。在这一点上可能更快，但我无法弄清楚这一点让我感到沮丧！

这是我当前的 .bat 文件：
