Windows批处理脚本考虑带空格的可执行文件的路径

Question

我有 Windows 批处理脚本

calculate.bat

，如下所示：

@echo on

REM check if the user has provided the expected number of arguments
if "%~2"=="" (
  echo Usage: %0 ^<directory location of dll files^> ^<directory location of calculate executable^>
  exit /b 1
)

set "search_dir=%~1"
set "calc_path=%~2"

cd  C:\tmp\xyz.d\

if exist checksum_file (
  del checksum_file
)

set "calc_exe=%calc_path%\calc.exe"


REM iterate over all .dll files in the search directory
for %%I in ("%search_dir%\*.dll") do (

REM #working with calc_exe path without spaces,but does not work with path having spaces
for /F %%A in ('%calc_exe% "%%I"') do echo %%I %%A >> checksum_file

)

如果传递的第二个参数的路径没有空格，则它可以工作

"C:\Working\test\bin"

。 例如：

calculate.bat "C:\Program Files\test\Windows-x86-64" "C:\Working\test\bin"

但是如果我用空格传递第二个参数的路径

"C:\Program Files\test\bin"

： 例如：

 calculate.bat "C:\Program Files\test\Windows-x86-64" "C:\Working\test\bin"

它不起作用并给出如下错误：

 for /F %A in ('C:\Program Files\test\bin\calc.exe "C:\Program Files\test\Windows-x86-64\sample.dll"') do echo C:\Program Files\test\Windows-x86-64\sample.dll %A  1>>checksum_file
)
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

这是直到第一次出现空格为止的考虑路径。

您面临的问题是因为批处理脚本中的

for /F

循环将空格分隔的值视为单独的标记。因此，当您传递带有空格 (

C:\Program Files\test\bin

) 的路径时，它会将

C:\Program

和

Files\test\bin

视为两个令牌并尝试执行它们（一个接一个），从而导致您看到的错误。

@echo on

REM check if the user has provided the expected number of arguments
if "%~2"=="" (
  echo Usage: %0 ^<directory location of dll files^> ^<directory location of calculate executable^>
  exit /b 1
)

set "search_dir=%~1"
set "calc_path=%~2"

cd C:\tmp\xyz.d\

if exist checksum_file (
  del checksum_file
)

set "calc_exe=%calc_path%\calc.exe"

REM iterate over all .dll files in the search directory
for %%I in ("%search_dir%\*.dll") do (

  REM #working with calc_exe path with spaces
  for /F %%A in ('"%calc_exe%" "%%I"') do echo %%I %%A >> checksum_file

)

通过在 for /F 循环中将

%calc_exe%

括在双引号内，整个路径将被视为单个标记，并且脚本将正确处理包含空格的路径。

现在，您可以像这样执行批处理脚本：

calculate.bat "C:\Program Files\test\Windows-x86-64" "C:\Working\test\bin"
