使用 Windows 批处理命令循环直到文件存在 [英] Loop until file exists using windows batch command

问题描述

如何将以下代码转换为 Windows 批处理命令?

how can i convert following code into windows batch command?

这是一个 perl 脚本，它在 while 循环中搜索文件，如果找到则退出.

Here is a perl script which is searching for a file in a while loop, if found it Exits.

use strict;
use warnings;
my $filename = 'something.txt'; 
while (1) {

if (-e $filename) {
print "File Exists!";
   exit;
   }

}

推荐答案

这是一个相当直接的翻译.代码应该一目了然:

This is a fairly straight-forward translation. The code should be pretty self-explanatory:

@ECHO OFF
SET LookForFile="C:PathToFile.txt"

:CheckForFile
IF EXIST %LookForFile% GOTO FoundIt

REM If we get here, the file is not found.

REM Wait 60 seconds and then recheck.
REM If no delay is needed, comment/remove the timeout line.
TIMEOUT /T 60 >nul

GOTO CheckForFile


:FoundIt
ECHO Found: %LookForFile%
