引用可能以反斜杠结尾的Windows批处理参数

batch-file windows

假设我想打电话给Robocopy复制 *.foo A:\ B:\

robocopy A:\ B:\ *.foo

%~1

robocopy "%SOURCE%" B:\ *.foo

不幸的是,如果 %SOURCE% \ "

robocopy "A:\" B:\ *.foo

所以Windows认为第一个参数是 "A:" B:\ *.foo

我怎样才能关掉对 \"

\\ \ ,第一个反斜杠逸出第二个,再也没有任何内容逸出。

<command> "this\is\a\path\\" "\this\is\another\path\\"

robocopy

robocopy "this\is\a\path" "this\is\another\path" <args>

%SOURCE%=%SOURCE:\=\\%

之后,您可以使用 %SOURCE%

我建议使用像这样的批处理文件:

@echo off
if not exist %SystemRoot%\System32\robocopy.exe goto BatchHelp
if "%~1" == ""   goto BatchHelp
if "%~1" == "/?" goto BatchHelp
if "%~2" == ""   goto BatchHelp

call :CleanPath SOURCE %1
call :CleanPath DESTINATION %2

%SystemRoot%\System32\robocopy.exe "%SOURCE%" "%DESTINATION%" *.foo

rem Delete the used environment variables.
set "SOURCE="
set "DESTINATION="

rem Avoid a fall through to the subroutine CleanPath.
goto :EOF

rem The subroutine CleanPath must be called with two arguments.
rem The first one must be the environment variable which should hold the
rem cleaned folder path for usage with ROBOCOPY. The second argument must
rem be the folder path which should be cleaned for usage with ROBOCOPY.

:CleanPath
rem Get full absolute path of folder path. This reduces a lot of variants
rem which could occur on batch file called with various relative paths.
set "FolderPath=%~f2"

rem Does the folder path not end with a backslash?
if not "%FolderPath:~-1%" == "\" goto HavePath

rem Does the folder path have just three characters and is ending with
rem a colon and a backslash? Yes, append an escaping backslash at end.
rem Otherwise the folder path of a folder not being the root folder
rem of a drive ends with a backslash which must be removed to get
rem the folder path correct interpreted by ROBOCOPY.
if "%FolderPath:~1%" == ":\" (
    set "FolderPath=%FolderPath%\"
) else (
    set "FolderPath=%FolderPath:~0,-1%"
)

:HavePath
set "%~1=%FolderPath%"
set "FolderPath="

rem Return to calling routine.
goto :EOF


:BatchHelp
cls
echo Usage: %~nx0 source destination
echo/
echo        source ... source directory
echo   destination ... destination directory
echo/
echo This batch file requires ROBOCOPY in Windows system directory.
echo/
pause

call /?
cls /?
echo /?
goto /?
if /?
pause /?
rem /?
robocopy /?
set /?
