how can i convert following code into windows batch command?
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;
}
}
This is a fairly straight-forward translation. The code should be pretty self-explanatory:
@ECHO OFF
SET LookForFile="C:\Path\To\File.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%
%. The OP original code did not have a delay, so why do you? If you do introduce a delay using TIMEOUT, then you should redirect stdout to nul and use /NOBREAK option.
CMD will enter a hard loop and absolutely eat CPU.
