Windows cmd .bat - 启动与父进程同时运行的子进程，并在父进程关闭时关闭

Question

所以这可能是不可能的，但我还是会问

我有一个日志 .bat 脚本，旨在收集应用程序的信息和使用时间。所以我想要的是一个批处理文件，它要求用户提供一些基本信息，启动一个子进程或 .bat 文件，允许用户输入更多信息，而父进程启动并等待 Windows 应用程序(例如记事本)。 EXE文件)。然后，我希望在用户关闭 notepad.exe 后父进程和子进程退出。

总的来说，这就是我到目前为止所拥有的；

@echo off

set someinfo=
set /p someinfo="Enter Some Info Please: "
For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set mydate=%%b/%%a/%%c)
For /f "tokens=1-2 delims=/:" %%a in ("%TIME%") do (set mytime=%%a:%%b)

:: Starting time and info
echo %someinfo%,%mytime%,%mydate% >> C:\Temp\MSuser.log 

:: This would be the child process for additional input 
start "Additional info" addinfo.bat 

::This is the software I want to start
start /Wait "" "C:\Program Files (x86)\notepad.exe"


:: Once user exits software write log string and exit .bat file
For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set mydate=%%b/%%a/%%c)
For /f "tokens=1-2 delims=/:" %%a in ("%TIME%") do (set mytime=%%a:%%b) 

:: Ending time and info
echo %someinfo%,%mytime%,%mydate% >> C:\Temp\MSuser.log 

问题是当子进程启动“addinfo.bat”时，父进程会等待子进程完成，然后再继续执行下一行代码(start/Wait """C:\Program Files (x86)\notepad .exe”)

是否可以同时运行子进程并继续父进程？此外，有没有办法在退出父进程之前强制子进程关闭，也许是“killpid”之类的东西？

这将从您的子进程获取PID，并在父进程完成时杀死它:

@echo off

set someinfo=
set /p someinfo="Enter Some Info Please: "
For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set mydate=%%b/%%a/%%c)
For /f "tokens=1-2 delims=/:" %%a in ("%TIME%") do (set mytime=%%a:%%b)

:: Starting time and info
echo %someinfo%,%mytime%,%mydate% >> C:\Temp\MSuser.log 

:: This would be the child process for additional input 
start "Additional info" adinfo.bat

::This is the software I want to start
start /Wait "" "notepad.exe"

:: Once user exits software write log string and exit .bat file
For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set mydate=%%b/%%a/%%c)
For /f "tokens=1-2 delims=/:" %%a in ("%TIME%") do (set mytime=%%a:%%b) 

:: Ending time and info
echo %someinfo%,%mytime%,%mydate% >> C:\Temp\MSuser.log

for /f "tokens=2 delims=," %%a in ('tasklist /v /fo csv ^| findstr /i "Additional info"') do set "$PID=%%a"
taskkill /PID %$PID%
