    With a number of searches I've put together a script that will email me a list of empty directories on our SAN. The email works, and sends me a rather ugly list on one line:

    \\sann\rdb$\RDT00437 \\sann\rdb$\TEST0 \\sann\rdb$\TEST1

    When I try to pipe it to FORMAT-LIST I get garbage (times 3):

    Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData

    How can I format the list to look like:

    \\sann\rdb$\TEST0
    \\sann\rdb$\TEST1
    \\sann\rdb$\TEST2

    Code:

    $mailto2 = "space.manager@xxxxxx.com
    $day_of_week = get-date -uformat "%A"
    $empty_dir = get-childitem \\sann\rdb$\ | Where-Object { $_.PSIsContainer } |
    Where-Object { $_.GetFiles().Count -eq 0 } |
    Where-Object { $_.GetDirectories().Count -eq 0 } | ForEach-Object {$_.FullName} | sort
    $smtpServer = "yyyyyyy.xxxxxx.com"
    $smtp = New-Object Net.Mail.SmtpClient($smtpServer)
    $msg = New-Object Net.Mail.MailMessage
    $msg.From = "abc@xxxxxx.com"
    $msg.Subject = $mailsubject + $day_of_week
    $msg.IsBodyHTML = $false
    $msg.Body = $empty_dir
    $msg.To.Add($mailto2)
    $smtp.Send($msg)

    To answer your question, you are creating a string doing the for loop: ForEachObject{$_.FullName}

    Have you looked at using HTML reporting? Don Jones put together a free e-book on it and there are various other articles on Powershell HTML reporting. Basically:

    • Remove the ForEach logic
    • Update .IsBodyHTML to $true
    • Update .Body to ($empty_dir |ConvertTo-Html | Out-String)

    The Body parameter of Send-MailMessage (or property of the MailMessage class, in this case) takes a String, and you're passing it an Array. Arrays, when automatically converted to strings, are separated by the output field separator ($OFS), which defaults to a space.

    The simplest way to get what you see at the console is to pipe your array to Out-String before assigning it to the Body property:

    $msg.Body = $empty_dir | Out-String
