Note: works only with V2 which is currently in CTP stage!

The command below will show you a very nice overview of disk size & free space for a list of computers (input file). The great thing about PowerShell, from my point of view, is “piping” commands into 1 big command which eliminates the need to create a script for certain operations. Secondly in V2 (CTP), the “gridview” option is amazing!

Get-WMIObject Win32_LogicalDisk -filter “DriveType=3″ -computer (Get-Content c:\scripts\computers.txt) | Select SystemName,DeviceID,VolumeName,@{Name=”size(GB)”;Expression={”{0:N1}” -f($_.size/1gb)}},@{Name=”freespace(GB)”;Expression={”{0:N1}” -f($_.freespace/1gb)}} | Out-GridView

thanks for the script…works great…how do i get this to output to a file and send an email to myself?

I tried to pipeline to csv or txt…but it failed. shouldnt it just be this:

Get-WMIObject Win32_LogicalDisk -filter “DriveType=3″ -computer (Get-Content c:\scripts\computers.txt) | Select SystemName,DeviceID,VolumeName,@{Name=”size(GB)”;Expression={”{0:N1}” -f($_.size/1gb)}},@{Name=”freespace(GB)”;Expression={”{0:N1}” -f($_.freespace/1gb)}} | Export-CSV drivesizes.csv

$msg = new-object Net.Mail.MailMessage
$att = new-object Net.Mail.Attachment($filename)
$smtp = new-object Net.Mail.SmtpClient($smtpServer)

$msg.From = “admin”
$msg.To.Add(”admin”)
$msg.Subject = “drive size”
$msg.Body = “The drive size file is attached”
$msg.Attachments.Add($att)

$smtp.Send($msg

Am I missing something? any help will be appreciated…thanks.

Get-WMIObject Win32_LogicalDisk -filter “DriveType=3″ -computer (Get-Content c:\computers.txt) | It’s not working for me… what am I doing wrong. I have version 2.

Select SystemName,DeviceID,VolumeName,@{Name=”size(GB)”;Expression={”{0:N1}” -f($_.size/1gb)}},@{Name=”freespace(GB)”;Expression={”{0:N1}” -f($_.freespace/1gb)}} | Out-GridView

Figured it out. The script didn’t copy over properly.
