Hi Monks!,
I have the following subroutine: 
my $DEBUG_FILE = "log"; # Global

sub debug {
    my ($t) = @_;
    return 0 unless(defined($DEBUG_FILE));
    open my $fh, ">>",$DEBUG_FILE or return 0;
    my $prefix = "[".get_date()."][".basename($0)."](".$$."):";
    print $fh $prefix.$t."\n";
    close ($fh);
    return 1;
}

This subroutine gets a string and logs it into a debug file. This file is for the user to see the progress/errors of using my tool.
I have a few steps in the tool and each one (**could**) take some time. For example, one of the steps, takes an array of paths @paths and do some operation on each path. The operation takes some time so the whole step is long. I want to notify the user of the progress of this step.
In my head I have the following idea: Update the latest line of the debug file with the progress bar. The progress bar would look something like: 
[07/10/21 17:56:57][run.pl](211653):<some info example1>
[07/10/21 17:57:57][run.pl](211653):<some info example2>
[07/10/21 17:58:57][run.pl](211653):<some info example3>
[07/10/21 17:59:57][run.pl](211653):Running operation <operation>. Pro
+gress: 57%.

Then it will update it to be: 
[07/10/21 17:56:57][run.pl](211653):<some info example1>
[07/10/21 17:57:57][run.pl](211653):<some info example2>
[07/10/21 17:58:57][run.pl](211653):<some info example3>
[07/10/21 18:05:57][run.pl](211653):Running operation <operation>. Pro
+gress: 58%.

Note that it won't add a new line, it will update the old line.
Also the progress percentage is calculated with 100*$handled_paths/$paths_amount where $paths_amount=scalar(@paths) and $handled_paths is the current handled path.
I think that I could just go to the debug file, and just update the latest line each time - but is it the recommended way to do this?
