如何在我启动一个程序的地方编写批处理文件，当该程序完成或关闭时，启动另一个程序

Question

For example:

@echo off
start C:\Windows\system32\dfrgui.exe /C

Wait for defragmentation to finish.

start C:\"Program Files (x86)"\CCleaner\CCleaner.exe /AUTO

Wait for CCleaner to finish.

start C:\Windows\system32\cleanmgr.exe /sagerun:1

and so on.. You get the point. How I can do this? Thanks.

Answer 1

Start can take a command line argument /WAIT eg

@echo off
title Test cmd start

start /WAIT wait.cmd 5
start /WAIT cmd /k echo launched second command

pause

This simple example uses another script I have written (wait.cmd shown below) as the first command executed, as you will see if you test this with the /WAIT option specified the script allows the first command to finish before continuing:

@echo off
rem call with # of seconds to wait

set /a secs=%1
set /a ms=%secs%*1000
echo Process will wait for %secs% seconds and then continue...
ping 1.1.1.1 -n 1 -w %ms% > nul
echo.
exit

As a side note if you open a cmd session you can find out about the arguments that a command such as start accepts eg

Update following comment

So to adapt the commands you listed in your question to finish before starting the next command in the script you could use:

@echo off
start /WAIT C:\Windows\system32\dfrgui.exe /C
start /WAIT C:\"Program Files (x86)"\CCleaner\CCleaner.exe /AUTO
start /WAIT C:\Windows\system32\cleanmgr.exe /sagerun:1
