Question

我正在尝试创建一个小型批处理文件，它将启动程序并更改计算机的时间，并在程序关闭时更改时间。

我的程序并没有真正起作用，所以我在寻求你的帮助。这是我到目前为止所得到的：

:Item_1
tzutil /s "Hawaiian Standard Time"

:Item_2
tzutil /s "W. Europe Standard Time"

@echo off
Start ""  "C:\Program Files (x86)\Minecraft\MinecraftLauncher.exe"
set Programma="C:\Program Files (x86)\Minecraft\MinecraftLauncher.exe"
tasklist |find /i "%Programma%"nul
if %errorlevel% == 0 (
'%t%' == '%t%' GOTO Item_%1%
) else (
'%t%' == '%t%' GOTO Item_%2%
)

Answer 1

goto就是这样说的。它转到标签。而已。在那里，cmd继续＆＃34;像往常一样＆＃34; - 逐行。所以它tzutil /s "Hawaiian Standard Time"，紧接着是tzutil /s "W. Europe Standard Time"

表达式'%t%' == '%t%'似乎完全是胡说八道。

遵循脚本的逻辑，它可以简化为：

@echo off
set "Programma=C:\Program Files (x86)\Minecraft\MinecraftLauncher.exe"
Start ""  "%Programma%"
tasklist |find /i "%Programma%">nul
if %errorlevel% == 0 (
  tzutil /s "Hawaiian Standard Time"
) else (
  tzutil /s "W. Europe Standard Time"
)

Answer 2

@echo off
setlocal enableextensions

rem before launching minecraft change the TZ to EU.
tzutil /s "W. Europe Standard Time"

set "Programma=C:\Program Files (x86)\Minecraft\MinecraftLauncher.exe"
Start ""  "%Programma%"

rem give a break of 3mins before starting the loop
@timeout /T 180 /nobreak >nul

:isrunning
tasklist /FI "IMAGENAME eq MinecraftLauncher.exe" /FI "STATUS eq running" /NH /FO csv | findstr /ic:"MinecraftLauncher.exe" >nul
if errorlevel 0 (
    rem :: Software found, then wait 3 mins before another loop
    @timeout /T 180 /nobreak >nul
    goto isrunning
) else (
    rem :: Software not found, we can now change the TZ before exit.
    tzutil /s "Hawaiian Standard Time"
    exit /b 0
)

如何通过启动和结束程序来更改计算机的时间？
