Question

这是我遇到的问题：

@ECHO OFF

REM If this batch file is run in the same directory as "command.exe" then the
REM following line will work.
FOR /F "usebackq" %%A IN (`command.exe "C:\File Being Passed as a Parameter.txt"`) DO ECHO %%A

REM The following line does not work no matter where this batch file is run.
FOR /F "usebackq" %%A IN (`"C:\Folder With Spaces\command.exe" "C:\File Being Passed as a Parameter.txt"`) DO ECHO %%A

我想将此批处理文件存储在任何我想要的位置，而不是强制将其存储在与command.exe相同的文件夹中。有什么建议吗？

Answer 1

在程序名称前添加CALL：

FOR /F "usebackq" %%A IN (`CALL "C:\Folder With Spaces\command.exe" "C:\File Being Passed as a Parameter.txt"`) DO ECHO %%A

Answer 2

Andriy M的call技巧很聪明且工作正常，但我试图在这里理解这个问题。

此问题是由cmd.exe引起的，您可以在cmd /help

阅读

....
  当有时，第一个和最后一个引用将被删除   不完全是两行中的引号。
  ...

因此，还有另一种解决方案，只需添加两个额外的引号

FOR /F "usebackq=" %%A IN (`""C:\Folder Space\myCmd.exe" "Param space""`) DO (
    ECHO %%A
)

Answer 3

<强>小心：

使用＆＃39;来电＆＃39; （如Andriy M所示）似乎是最安全的选择。

我发现添加前导和尾随双引号的情况（如jeb的可能解决方案所示）存在问题。

<强>问题：

for /f "delims=" %%i in ('""C:\path with spaces\hello.bat" "filename with an & ampersand.jpg""') do ( echo output=%%i )

cmd.exe的输出：& was unexpected at this time.

<强>解决方案：

for /f "delims=" %%i in ('call "C:\path with spaces\hello.bat" "filename with an & ampersand.jpg"') do ( echo output=%%i )

批处理文件：如果路径有空格，则FOR / F不起作用
