Question

我在编写批处理脚本时遇到了这个小问题。

:Delete_File
cls
title Delete File
echo Welcome to the Utility Delete File!
echo Type the name of the file you want to delete:
echo.
set /p var=
echo.
echo I'm checking the existance of the file...
ping 192.0.2.2 -n 1 -w 2000>nul
if EXIST %var% del %var%
if NOT EXIST %var% echo The file doesn't exist. Check for errors and try again. 
ping 192.0.2.2 -n 1 -w 1500>nul
set /p answer=1 - Go to Menu _ 2 - Go to Exit 
if %answer%==1 goto Menu
if %answer%==9 goto Exit

所以，问题是当文件成立时，它会被删除，但它会显示第12个字符串中的消息。我需要显示消息＆＃34;文件已成功删除！将您重定向到菜单...

echo The file was successfully deleted!
echo Redirecting you to the Menu...
ping 192.0.2.2 -n 1 -w 2000>nul
goto Menu

我对这个问题的错误语法感到非常抱歉，但我是新的。感谢我得到的每一个回复！费德里科。

Batch实际上不是执行此类项目的最佳语言，但您应该颠倒IF EXIST和IF NOT EXIST行的顺序。删除IF EXIST行中的文件后，该文件不再存在，并且之后立即执行IF NOT EXIST测试将成功。

如果您遇到其他问题，可以使用多个标签，例如：

if NOT EXIST %var% goto :DeleteFileMissing
del %var%
Goto :DeleteFileContinue

:DeleteFileMissing
echo The file doesn't exist. Check for errors and try again. 

:DeleteFileContinue

问：如果EXIST / IF不存在于批处理脚本中
