Thanks. I modified the script again based on your suggestions. E.g. from
this script I get
The total size of the file in etc is 15712.35 Kb
The total size of the file in etc is 15.34 Mb
and when I check this from Win XP Explorer (folder properties) window I get
Size: 372 KB (380 928 bytes)
What is the reason for this difference?
-L
---code---
#!/bin/perl
use warnings;
use strict;
use File::Find;
my $dir = $ARGV[0];
die "You must supply a full directory path" unless (-e $dir && -d $dir);
opendir (DIR, $dir) or die "can't opendir $dir: $!";
my @directories = grep {! /^\./ if -d} readdir(DIR);
my $total_size_of_files_in_dir;
foreach my $dir (@directories) {
find(\&wanted, $dir); ### Not sure how that worked as you called
it $directory
print "The total size of the file in $dir is " . sprintf("%.2f
Kb", ($total_size_of_files_in_dir * 0.0009765625)) . "\n";
print "The total size of the file in $dir is " . sprintf("%.2f
Mb", ($total_size_of_files_in_dir * 9.5367431641e-7))
. "\n"
}
sub wanted {
if (-f $_) {
$total_size_of_files_in_dir += -s;
}
}
