loading/processing animation in perl

Is there a way to display an animation while Perl is processing a file or something else? Maybe the sequence of | / - | \ (rotating pipe) instead of just printing dots.

Thanks for your help.


The simple rotating pipe can be created using code like this:


use strict;
use warnings;

$|++; # turn off output buffering;

my @chars = qw(| / - \ );

my $i = 0;

print $chars[$i];

while (1) {
  sleep 1;
  print "\b", $chars[++$i % @chars];

For something more complex, take a look at Term::ProgressBar.
