先看代码：
@echo off :get_key set "key=" for /f "delims=" %%a in ('xcopy /w "%~f0" "%~f0" 2^>nul') do if not defined key set "key=%%a" set "key=%key:~-1%" echo %key% pause

这个方式好象能支持比 choice 更多的字符, 比如 , . / Tab 字符, 甚至组合键 Ctrl+A Ctrl+Q 等
另外, 我把参数稍改了下, 在 win7 64 位仍能行
| xcopy /w . . 2^>NUL | |
| 或者 | |
| xcopy /w \ \ 2^>NUL |

随后, jeb 又在 stackoverflow 和 groups.google.com/forum 都发表过此代码应用例

我找到的时间最早的示例代码：
@echo off setlocal EnableDelayedExpansion if "%~1"==":::" goto :spinnerThread :menuLoop <nul set /p menu=Select menu[1 or 2]= call :GetKey echo( echo Pressed '!key!' if !key!==1 call :menu1 if !key!==2 call :menu2 if !key!==2 call :menu2 goto :menuLoop :menu1 :menu2 call :spinnerStart rem do some work ping localhost -n 3 > nl call :spinnerStop echo Finished exit /b :spinnerStart del spinnerStop.tmp > nul 2>&1 start /b "" cmd /c "%~df0" ::: exit /b :spinnerStop echo dummy > spinnerStop.tmp :__spinnerStop if exist spinnerStop.tmp goto :__spinnerStop exit /b :spinnerThread for /f %%a in ('copy /Z "%~f0" nul') do set "CR=%%a" set "spinChars=\|/-" :spinnerLoop set /a "spinner=(spinner + 1) %% 4" <nul set /p ".=Waiting...!spinChars:~%spinner%,1!!CR!" ping localhost -n 2 > nul 2>&1 if not exist spinnerStop.tmp goto :spinnerLoop del spinnerStop.tmp > nul 2>&1 echo( exit /b :GetKey set "key=" for /F "usebackq delims=" %%L in (`xcopy /L /w "%~f0" "%~f0" 2^>NUL`) do ( if not defined key set "key=%%L" ) set "key=%key:~-1%" exit /b

再简化：
xcopy /w . 2^>NUL话说从链接中看到了熟悉的...
for /f %%a in ('copy /Z "%~dpf0" nul') do set "CR=%%a" For /F delims^=^ eol^= %%Z in ("!Char!") Do Set "Intro=0" Echo(
看来歪果仁也发现了这些
