[英]Batch file that deletes itself and folder that contains it
I'm trying to do the following but deleting the downloaded folder which contains the batch file fails: NOTE: All exe's, apps, batch file etc. are contained in file.zip. 我正在尝试执行以下操作,但是删除包含批处理文件的下载文件夹失败:注意:所有exe,应用程序,批处理文件等都包含在file.zip中。
Below is the batch file: 下面是批处理文件:
@echo off
mode con: cols=32 lines=7
color 4f
title
echo 30 Second Delay
echo Close window to abort
echo/
echo/
echo 0%% 100%%
SET /P var= <NUL
set count=0
:loop
PING -n 2 127.0.0.1 >NUL 2>&1
call :printline _
set /a count=count+1
if %count%==30 goto finish
goto loop
:printline
REM Print text passed to sub without a carriage return.
REM Sets line variable in case %1 intereferes with redirect
set line=%1
set /p var=%line%<NUL
exit /b
:finish
cls
color 0f
title Finished
mode con: cols=80 lines=25
echo Do NOT close this window!
echo/

timeout /t 5 >nul
echo Do NOT close this window!
echo/
rem echo Restarting Windows Explorer...

rem taskkill /f /im explorer.exe >nul
rem start explorer.exe
echo Do NOT close this window!
echo/
echo Deleteing files and folders...
echo/
rem timeout /t 10 >nul
Set "Folder2Del=%~dp0"
cd ..
IF EXIST "file.zip" DEL "file.zip" /s /q >nul
rem echo %scrptDir%
echo Do NOT close this window!
echo/
echo Still working...
timeout /t 10 >nul
rd %Folder2Del% /s /q
(goto) 2>Nul & RD /S /Q "%Folder2Del%" & exit
The problem I encounter is that the folder never gets deleted. 我遇到的问题是该文件夹永远不会被删除。 I realize my code is not correct but another reason is because one of the dll files in the unzipped folder is sometimes still in use by the dllhost.exe process.
我意识到我的代码不正确,但是另一个原因是因为dllhost.exe进程有时仍在使用解压缩文件夹中的一个dll文件。
I'm not sure if it is safe to add a line that kills the dllhost.exe process or not but my code still won't work because I have something wrong with how it deletes the batch file itself and the folder that contains it. 我不确定添加是否可以杀死dllhost.exe进程的行是否安全,但是我的代码仍然无法正常工作,因为我在删除批处理文件本身以及包含该批处理文件的文件夹时遇到了问题。
What lines do I need to edit and is it safe to kill dllhost.exe? 我需要编辑哪些行?杀死dllhost.exe是否安全?
According to a link from dbenham 根据dbenham的链接
This does the trick: 这可以解决问题:
@Echo off
Echo Ref: "http://www.dostips.com/forum/viewtopic.php?f=3&t=6491"
Set "Folder2Del=%~dp0"
cd "%~d0"
pause
(goto) 2>Nul & RD /S /Q "%Folder2Del%"
Take care the folder containing the batch is deleted 注意删除包含该批次的文件夹
including any other files/folders without any further question! 包括任何其他文件/文件夹,没有任何其他疑问!
Ok... I THINK I figured out how to do what I want by trying to delete the dll file, first, before trying to delete the entire directory. 好吧...我想,我想出了要通过尝试删除dll文件来完成我想做的事情的方法,首先是在尝试删除整个目录之前。 The code below looks for the problem dll and tries to delete it.
下面的代码查找有问题的dll,然后尝试将其删除。 If it still exists, it will try to delete the file every 30 seconds for up to 15 minutes.
如果仍然存在,它将尝试每30秒删除一次文件,最多15分钟。 As soon as the dll gets deleted, the entire folder will also be deleted.
一旦dll被删除,整个文件夹也将被删除。 If after 15 minutes the dll cannot be deleted, the remaining files in the folder will be deleted.
如果15分钟后无法删除该dll,则该文件夹中的其余文件将被删除。
I still have a small issue. 我还有一个小问题。 If I add code that kill/restarts Windows Explorer, the folder does not get deleted.
如果添加杀死/重新启动Windows资源管理器的代码,则不会删除该文件夹。 Why and is there a workaround?
为什么并且有解决方法?
