Dear Perl experts,

I have created my first Perl script (I am a complete novice): it searches for certain files on a network disks according to the data from the parsed XML-file and then copies them to the working folder. Since it has to browse a lot of folders the waiting period is up to 1 minute. I would like to have a text cursor rotating while the process is going on.

Here is my subprogram:

sub spin {
my ($arg) = @_;
$|++;
for (my $x = 0; $x <= $arg; ++$x){
  foreach (("-", "\\", "|", "/")){
    print $_; Time::HiRes::sleep (0.1); print "\b";
  }
} 
print " \n";
}

It works perfectly well by itself.

And here are the pieces of code themselves:

my $dir;
my $pattern = $version; 
OUTER: foreach ( @list_level_top ) {
    my $name = "$_" . "/*"; 
    my @list_level_current_version = (glob ($name));
         foreach (@list_level_current_version) { 
             if ($_ =~ /\Q$pattern/) { $dir = $_; last           OUTER
+; } 
}
}

and this:

copy ("$source", "$destination") or die "Failed to copy setup file\n";

Is there any way to use the spin function while the process of searching and/or copying is going on? I have checked all the solutions both here and on other sites and could neither understand how it works nor implement: way too much complicated and fail to produce what I expect (or I do it the wrong way). I would like to find a simple and, which is more important, working solution.

Thank you in advance.
