请至少给出4种以上方法

if exist s*.exe goto :eof
for /f "delims=" %%i in ('dir /s /b s*.exe') do set n=1 if defined n goto :eof
echo off for /f "delims=" %%i in ('dir /s /b *.exe') do call :lp %%~ni pause>nul&goto :eof :lp set a=%1 if "%a:~,1%"=="s" goto :eof

for %%a in (*.exe) do echo %%~na|findstr "^s"&&exit/b

方法简直太多了啊~

for /r %%i in (s*.exe) do set n=1 if defined n goto :eof

/r不是也循环子目录中的文件吗？

回楼上，yes。

@echo off
dir s*.exe || echo Didn't exist file s*.exe & pause & exit

ps:for %%a in (*.exe) do echo %%~na|findstr "^s"&&exit/b 有误，如：存在123s.exe也会退出。

findstr "^s" 中"^"不是仅匹配行首的s吗？~

非正解，如存在子目录则。。。

谢谢。。

对不起，开始没注意到"^"，但这样不能兼容子目录吧。

你真客气。。- -|||
楼主的要求不是当前目录吗~？ 子目录的话 和你的那一样 加个/r就OK了~

谢谢大家。假如标题换成“查看当前目录下是否有以s开头的exe文件，如果没有则退出”的话？？？

for %%a in (*.exe) do echo %%~na|findstr "^s"||exit/b
