How to wait for a process to terminate before executing another process in a batch file? Let's say I have a process notepad.exe that I need to kill before executing wordpad.exe. Then, when wordpad.exe is terminated, I need to launch notepad.exe again. How do I do that?

推荐答案

试试这样...

@ECHO OFF

PSKILL NOTEPAD

START "" "C:Program FilesWindows NTAccessorieswordpad.exe"

:LOOP
PSLIST wordpad >nul 2>&1
IF ERRORLEVEL 1 (
  GOTO CONTINUE
) ELSE (
  ECHO Wordpad is still running
  TIMEOUT /T 5
  GOTO LOOP
)

:CONTINUE
NOTEPAD

我使用了 PSLIST 和 PSEXEC，但你也可以使用 TASKKILL 和 TASKLIST.>nul 2>&1 只是为了隐藏 PSLIST 的所有输出.SLEEP 5 行不是必需的，只是用来限制您检查写字板是否仍在运行的频率.

I used PSLIST and PSEXEC, but you could also use TASKKILL and TASKLIST. The >nul 2>&1 is just there to hide all the output from PSLIST. The SLEEP 5 line is not required, but is just there to restrict how often you check if WordPad is still running.
