批處理腳本不會使用用戶輸入刪除 Temp 文件夾的內容

Question

@echo off

SET dir=%temp%
SET /p choice= Are you sure you want to delete your Temp Folder's contents? [y/n] 
IF /I "%choice%"=="y" (
    rmdir /s /Q %dir%
    mkdir %dir%
    Title Deleted Temp's contents
    echo Deleted Temp's contents
    timeout 2 > nul
    exit
)
IF /I "%choice%"=="n" (
    exit
) ELSE (exit)

我想自動刪除 Temp 文件夾。 我在 Windows 10 版本 2004 上運行這個批處理腳本

Answer 1

改用choice ，默認選項是Y/N 。 我也不會刪除整個臨時文件夾並重新創建，只需將其清除：

@echo off
choice /m "Are you sure you want to delete your Temp Folder's contents?"
if errorlevel 2 goto :eof
for /D %%i in ("%temp%\*") do rd "%%i" /S /Q
del "%temp%\*" /S /Q
Title Deleted Temp's contents
echo Deleted Temp's contents
timeout 2 > nul

Answer 2

Windows 無法刪除當前工作目錄，因此清空目錄的最佳方法是在嘗試刪除之前將其設為當前目錄。 這將實質上刪除所有允許的內容，而不會觸及目錄本身。 （注意：可能不會刪除所有內容，僅刪除未鎖定/未使用且您有足夠權限刪除的內容） 。

@Echo Off
SetLocal EnableExtensions

Rem If the directory to empty, has no file content, end the script.
"%__APPDIR__%where.exe" /Q /R "%TEMP%" * || (
    Echo %TEMP% has no file content.
    Echo Exiting . . .
    "%__APPDIR__%timeout.exe" /T 3 /NoBreak 1> NUL
    GoTo :EOF
)

Rem If the running script is in within, the directory to empty, end it.
SetLocal EnableDelayedExpansion
If /I Not "!__CD__:%TEMP%=!" == "%__CD__%" (
    Echo Cannot empty %TEMP% because this script is located within it.
    Echo Please move %~f0 to another location and try again.
    Echo Press any key to exit . . .
    "%__APPDIR__%timeout.exe" /T -1 1> NUL
    GoTo :EOF
)
EndLocal

Rem Make the directory to empty, the current working directory.
Rem If the directory to empty, cannot be found, end the script.
PushD "%TEMP%" 2> NUL || (
    Echo The directory assigned to %%TEMP%% cannot be found.
    Echo Exiting . . .
    "%__APPDIR__%timeout.exe" /T 3 /NoBreak 1> NUL
    GoTo :EOF
)

Rem If the end user answers N, or n, end the script.
"%__APPDIR__%choice.exe" /M "Are you sure you want to empty your Temp directory"
If ErrorLevel 2 (
    Echo Exiting . . .
    "%__APPDIR__%timeout.exe" /T 3 /NoBreak 1> NUL
    GoTo :EOF
)

Rem Empty permissible content from the current directory.
RD /S /Q . 2> NUL
Title Cleaned %CD%.
Echo Emptied permissible content from %CD%

Rem Make the previously current directory, current again.
PopD

Echo Press any key to exit . . .
"%__APPDIR__%timeout.exe" /T -1 1> NUL
GoTo :EOF

上面的代碼可能比其他答案有更多的內容，但它顯示了您在創建腳本時應該嘗試遵循的邏輯進程，尤其是那些正在刪除文件和目錄內容的腳本。

如果您不希望代碼結構經過深思熟慮，那么您可以這樣做：

@CD /D "%TEMP%" 2>NUL||Exit /B
@"%__APPDIR__%choice.exe" /M "Are you sure you want to empty your Temp directory"
@If ErrorLevel 2 Exit /B
@RD /S /Q . 2>NUL
@Title Cleaned %CD%.
@Echo Emptied permissible content from %CD%
@"%__APPDIR__%timeout.exe" /T 2 1>NUL
