呵呵，笨办法还有

@echo off 
set "path=C:\Documents and Settings\All Users"
for /l %%i in (1 1 10) do call set "path=%%path:*\=%%"
echo %path%
pause>nul

@echo off 
set "path=C:\Documents and Settings\All Users"
set "path=%path: =#%"
set "path=%path:\= %"
for %%i in (%path%) do set "path=%%i"
echo %path:#= %
pause>nul
复制代码

注：以下“函数”并不完善，请勿随便套用！

@echo off  & setlocal enabledelayedexpansion
set "path=C:\Documents and Settings\All Users"
call :GetTheStr "%path%"
echo %res%
pause>nul

:GetTheStr str
set "var=%~1"
if not "%var:~-1%"=="\" (
   set path=%var:~0,-1%
   set res=%var:~-1%%res%
   call :GetTheStr "!path!"
)
复制代码

呵呵，搞的跟 随风兄的机理一样了！

不过比你的还“傻”，哈哈
