batch-file – Batch – EnableDelayedExpansion,感叹号和文件/文件夹名称

2023年5月25日 330次阅读

我正在努力处理文件和文件夹名称上的感叹号(！).

我创建的批处理读取.txt文件的内容,并将列出的文件从文件夹排序到子文件夹中.

例如：

source.txt包含：file_1.zip和file_2.zip

名为system的文件夹包含file_1.zip,file_2.zip,file_3.zip等.

并且批处理读取source.txt并将这两个文件复制到system / source中.

我试图避免启用DelayedExpansion,但是在添加文件夹浏览器后,我找不到比使用它更好的方法.我需要它以我显示的方式启用：listSources和：listFolders
我现在的问题不是处理(！)文件夹名称(尽管允许它很好),但允许复制其名称上有(！)的文件.

我想逃避^^！ setlocal和endlocal之间的角色或切换,但我仍在学习如何正确使用它,因此不知道如何处理它.也许有更好的方法？ (我不是程序员！)

任何帮助将不胜感激！

最佳答案 当FOR变量包含！时,延迟扩展仅导致FOR循环内的问题.

如果从循环内调出一个：子例程,通常可以避免FOR循环中的延迟扩展.子例程将针对每次迭代进行重新分析,因此您可以使用常规％var％变量扩展.但是CALL大大降低了速度,所以我想避免它.

有一个简单的解决方案可以避免延迟扩展并避免调用 – 使用带有FINDSTR / N的DIR / B将行号注入目录输出,FOR / F可以轻松解析.

例如,以下是ListSources循环的解决方案：

for /f "delims=: tokens=1*" %%A in ('dir /b /a-d *.txt^|findstr /n "^"') do (
  set "mapArray[%%A]=%%B"
  set "count=%%A"
  echo %%A: %%B
)

您可以轻松地将相同的技术应用于第二个循环.

您仍然需要在其他非循环代码段中延迟扩展以扩展数组值.所以从禁用延迟扩展开始,然后启用它：whichSource,在第二个循环之前再次禁用它,然后在最后一个循环后再次启用它.请注意,您不能使用ENDLOCAL,否则您将丢失先前定义的数组值.因此,当您在禁用和启用延迟扩展之间切换时,您将创建一小堆SETLOCAL.
