You could use a recursive sub to get the size of each file in the path and accumulate de bytes and then return the total bytes accumulated.

That gives you the size of the directory, and then you need a reference to the maximum allowed size to be able to get a percentage.


#!/usr/bin/perl

our $used = get_used_space("/path/to/dir",10000000);

print "Used space -> $used %\n";

sub get_used_space {
    my $dir = shift;
    my $max = shift;

    if ($max <= 0) {
        return 0;
    }
    my $current_size = get_space($dir);
    return int(($current_size / $max) * 10000)/100;
}

sub get_space {
    my $dir = shift;
    my $d;
    my $bytes = 0;

    opendir($d,$dir);
    while (my $f = readdir($d)) {
        if ($f eq '.' || $f eq '..') {
            next;
        }
        my $file = "$dir/$f";
        if (-d $file) {
            $bytes += get_space("$file");
        }
        if (-f $file) {
            my $size = -s "$file";
            $bytes += $size;
        }
    }
    return $bytes;
}
