perl progress bar dialog


In perl how to show the percentage download when we download something wget ...

For example when we wget some software instead of showing the following ......
[root@server]# wget
=> `iptraf-2.7.0.tar.gz'

It will show on right hand side ...

1% of 100% complete


on left hand side it will show ...

[360/363496] bytes of download complete

Any other suggestions on "perl progress bar dialog" is welcome

This is an example. You need to install Term::ReadKey module from CPAN before you can run it.

#!/usr/bin/perl -w

$| = 1;

my $steps = 50;
my $columns = &getTerminalSize()->[1];

for (my $i=1; $i<=$steps; $i++) {
    my $percent = ($i/$steps*100);
    my $pbwidth = $columns-10;
    my $numhashes = ($i/$steps*$pbwidth);
    printf("\r% -${pbwidth}s% 10s", '#' x $numhashes, "[ " . $percent . "% ]");
    sleep 1;

sub getTerminalSize {
    use Term::ReadKey;
    my ($w, $h) = GetTerminalSize(STDOUT);
    if (!defined $w || !defined $h) {
        die "Cannot determine terminal size!";
    return [$h, $w];

Output looks like this:
#########                                                                [ 14% ]

Fine.. how do I integrate that with wget? And how can the script calculate the percentage value from the results of the wget .. instead of a fixed value defined in the script.

# 4  
Why do you have to integrate with wget? Why not just try LWP in perl instead, or WWW::Curl? I cannot think of any good way to do it unless you have access to a WWW library such as curl or LWP, that you can implement whatever status reporting with it.

Thank you for your tips... I am zero where it comes to programming.. but I do have the logic/ideas only. I am starting to learn programming.

Can you give me a script which shows... downloading for example:-

and showing the progress bar

which uses LWP in perl instead, or WWW::Curl
