文件始终存在批处理文件 [英] File Always Exist Batch file

问题描述

我有一批检查文件是否存在.请参见下面的代码.

I have a batch which check the existence of a file. Please see code below..

  @ECHO OFF

  REM Clear screen before executing other commands 
  CLS 

  SET WebConfig=C:\inetpub\wwwroot\ABC\Web.Config
  SET CodeLocation=C:\inetpub\wwwroot\ABC\*.*


  IF NOT EXIST %WebConfig% GOTO WebError

  :WebError
     ECHO Web.Config File doesn't Exist...
     pause
     GOTO:EOF

  ECHO Working.. 

执行批处理文件时，我始终会收到一个不存在的错误文件.即使该文件存在于define文件夹中..

When executing the batch file, i always receive an error file doesn't exist.. Even though the file exist in the define folder..

你们能帮助我吗?希望很快能收到您的来信.

谢谢

推荐答案

仔细查看此部分代码:

IF NOT EXIST %WebConfig% GOTO WebError
:WebError

现在文件存在时会发生什么?不要回答，这很夸张:-)

Now what happens when the file exists? Don't answer, it's rhetorical :-)

它会跳到下一行，即等待错误消息部分.

It drops through to the next line which is, wait for it, the error message section.

请尝试执行此操作，当if语句不跳转时，它将跳过错误消息部分:

Try this instead, it skips over the error message section when the if statement doesn't jump:

    if not exist %WebConfig% goto WebError
    goto WebOkay
:WebError
    echo Web.Config File doesn't exist.
    pause
    goto :EOF
:WebOkay
    echo Working.

也可以进一步简化为:

    if exist %WebConfig% goto WebOkay
    echo Web.Config File doesn't exist.
    pause
    goto :EOF
:WebOkay
    echo Working.
