等待可执行文件完成运行 [英] Wait for executable to finish running

问题描述

您可以在批处理文件中运行两个可执行文件，然后等待第一个进程结束再开始下一个进程吗?

Can you run two executables in a batch file and wait for the first process to end before starting the next?

推荐答案

使用开始/等待:

:NOTEPAD
start /wait notepad.exe
IF %ERRORLEVEL% == 0 goto NEXTITEM1
else goto QUIT

:NEXTITEM1
start /wait mplayer.exe
IF %ERRORLEVEL% == 0 goto NEXTITEM2
else goto QUIT

:NEXTITEM2
start /wait explorer.exe
IF %ERRORLEVEL% == 0 goto NEXTITEM3
else goto QUIT

:NEXTITEM3
REM You get the idea...

:QUIT
exit

此外，使用NT CMD而不是BAT(myscript.cmd).

In addition, use NT CMD rather than BAT (myscript.cmd).

为回应这些评论，从上面的脚本中删除了％ERRORLEVEL％周围的方括号.以下似乎表现出预期的效果:

In response to the comments, brackets removed from the above script around %ERRORLEVEL%. The following seems to behave as expected:

:NOTEPAD
start /wait notepad.exe || goto QUIT

:NEXTITEM1
start /wait mplayer2.exe || goto QUIT

:NEXTITEM2
REM You get the idea...

:QUIT
exit  

双管道之后的语句仅在失败之前执行.

The statement after the double-pipe only executes if what is before it fails.
