msensay has asked for the wisdom of the Perl Monks concerning the following question:

hello Monks. I'm looking to write a PERL script that mimics what SC-DiskInfo does. The reason I want to do this is because SC-DiskInfo utility only comes in a UI flavor without a command line interface

One of the peices of code from this post comes very close to what I want to do:
http://perlmonks.com/?node_id=421553

here is the code snippet I'm talking about:

#!/usr/bin/perl -l use strict; use warnings; use File::Find; @ARGV=grep {-d or !warn "`$_': not a directory!\n"} @ARGV; die "Usage: $0 <dir> [<dirs>]\n" unless @ARGV; my ($tot,$maxsz,$max,$n)=(0,0); find { no_chdir => 1, wanted => sub { return unless -f; $n++; $tot += my $sz=-s; ($max,$maxsz)=($_,$sz) if $sz >= $maxsz; } }, @ARGV; die "Found 0 files\n" unless $n; print <<"EOF"; Total files found: $n Total size: $tot Largest file: `$max' (size: $maxsz bytes) EOF __END__

However, it falls a little bit short of what I need. I think it probably only needs a few changes to get there. Basically, in addition to the totals already provided, I would like it to provide rollups for one level deep. Here is a simplified example. Take this structure:

c:\temp\folder_1\file1.txt 5KB
c:\temp\folder_1\folder_1a\file1a.txt 5KB
c:\temp\folder_1\folder_1b\file1b.txt 5KB
c:\temp\folder_2\file2.txt 5KB
c:\temp\folder_3


when calling the perl script on c:\temp the results should look something like this:

Directory
-----------
#ofSubDirs
-------------
#ofFiles
---------
size
----
folder_1 2 3 15KB
folder_2 0 1 5KB
folder_3 0 0 0KB


Total for c:\temp
-----------------
Total Files found: 4
Total Size: 20KB

This is basically what SC-DiskInfo provides in a UI when scanning a directory. Any takers? Thanks in advance for any wisdom.

    Have you looked at Win32::DirSize? It's cosiderably faster than File::Find.

    Ok, I've got something working. If anyone sees something horribly inefficient, please let me know. I'll look into Win32::DirSize if I see perf issues with this solution. Thanks.

    Any takers?

    Why not you?

      Fair point. I should take a crack at it first. Was hoping someone who has mastered File::Find would be able to do it quickly. I'll see what I can do. thanks.
