progress bar in command line perl script

I am trying to print progress in % in command prompt. But it is not working properly.

I want to print the progress as :: Status 10% Completed when 20% will complete it will show Status 20% Completed in that same place not in new line. Could you please help me.

Code::

$count++;
$per=($count/$total)*100;
print "\nStatus:  $per Completed.\r";
sleep 1;

The module Term::ProgressBar seems to be able to do what you're after.

Note, I haven't tried it.

Edit Well, out of curiosity, I have now tried a small script:

use warnings;
use strict;

use Term::ProgressBar;

my $total = 50;
my $progress_bar = Term::ProgressBar->new($total);


for my $i (1 .. $total) {

  sleep (1);

  $progress_bar->update($i);

}

It won't exactly print what you asked (eg Status nn% completed), instead, it does print a real progress bar, something like

  10% [=====                                              ]

Nevertheless, it seems to most simple and straight forward solution.
