“在这个时候出乎意料."
问题描述：
我在批处理文件上运行此命令:
I'm running this command on a batch file:
for %I in (*.txt *.doc) do copy %I c:\test2
...它不断返回:
我在这个时候出乎意料.
I was unexpected at this time.
这个错误的原因是什么?
What is the cause of this error?
答
如果您在批处理/cmd 文件中运行，则需要加倍 % 标记:
If you're running within a batch/cmd file, you need to double the % markers:
for %%i in (*.txt *.doc) do copy %%i c:\test2
单个 % 变体仅适用于命令行.
The single % variant only works from the command line.
