(OP)
Please refer to the code here...

my @failFs={};
#@files, $retruCounter to 3 and $notDone=1 initialised
while ($retryCounter>0 and $notDone==1)
{
    print "No of Files to go- " .scalar(@files);
    $ftp =Net::ftp->new($host, debug=>1,Passive=>1) or die "couldn't connect";
    $ftp->login($userID,$passwd) or die "couldn't login";
    foreach $eachRemoteFile(@files)
    {
        $locFile = File::Spec->catfile($sourceDir,$eachRemoteFile);  
           
           $ftp->get($eachRemoteFile,$locFile) or (push @failFs,$eachRemoteFile);    
          
    } #end foreach
    @files= @failFs;        #Files to be retried
    logDebug("No of files left-" . scalar(@files));
    if (scalar(@files)==1)
    {
        $notDone=0;
    }
    $ftp->quit();    ##Quit, retry to get the failed files, if needed
    
    $retryCounter--;
    
}#end while


The variable of interest is scalar(@files) at the end of the foreach.  What I am doing here is FTP files contained in the original @files array.
If it failed, then put in @failFs array.  At the end of the foreach{}. @files are set to @failFs.  I would like a short cut to quite the while loop when no files are left, rather than iterating through the noOfRetry times, but it seems like scalar(@files) is always=1 after the first iteration.  Why is that?

The problem is your definition of @failFs:

my @failFs={};

You are declaring @fileFs as an array and setting it's first element to a reference to an anonymous, empty hash. I tried that statement and then print @failFs and the first element contains a hash reference. Apparently, all your uploads are working successfully, so nothing else gets pushed into @failFs, but since it already contains one element (the hash ref) when you copy it to @files it also contains one element. What you meant to do to declare @failFs as an empty array is:

my @failFs=();

I.e. use parentheses instead of brackets (it's kind of hard to tell the difference in some fonts.
