You don't need expr for that, just backticks or $(...).
Code:
s=$(ls -s Documents | grep Music | awk '{print $1}')

File::HomeDir::Windows(3pm)				User Contributed Perl Documentation			       File::HomeDir::Windows(3pm)

NAME
File::HomeDir::Windows - Find your home and other directories on Windows SYNOPSIS
use File::HomeDir; # Find directories for the current user (eg. using Windows XP Professional) $home = File::HomeDir->my_home; # C:Documents and Settingsmylogin $desktop = File::HomeDir->my_desktop; # C:Documents and SettingsmyloginDesktop $docs = File::HomeDir->my_documents; # C:Documents and SettingsmyloginMy Documents $music = File::HomeDir->my_music; # C:Documents and SettingsmyloginMy DocumentsMy Music $pics = File::HomeDir->my_pictures; # C:Documents and SettingsmyloginMy DocumentsMy Pictures $videos = File::HomeDir->my_videos; # C:Documents and SettingsmyloginMy DocumentsMy Video $data = File::HomeDir->my_data; # C:Documents and SettingsmyloginLocal SettingsApplication Data DESCRIPTION
This module provides Windows-specific implementations for determining common user directories. In normal usage this module will always be used via File::HomeDir. Internally this module will use Win32::GetFolderPath to fetch the location of your directories. As a result of this, in certain unusual situations (usually found inside large organisations) the methods may return UNC paths such as "\cifs.localhome$". If your application runs on Windows and you want to have it work comprehensively everywhere, you may need to implement your own handling for these paths as they can cause strange behaviour. For example, stat calls to UNC paths may work but block for several seconds, but opendir() may not be able to read any files (creating the appearance of an existing but empty directory). To avoid complicating the problem any further, in the rare situation that a UNC path is returned by "GetFolderPath" the usual -d validation checks will not be done. SUPPORT
See the support section the main File::HomeDir module. AUTHORS
