Out-gridview does not sorting results

Question

I have a script that I am trying to collect drive letters from a list of servers (as well as used space and free space) and then gridview the results out.

$servers = Get-Content "path.txt"

foreach ($server in $servers) {
Invoke-Command -ComputerName $server {Get-PSDrive | Where {$_.Free -gt 0}}

Select-Object -InputObject usedspace,freespace,root,pscomputername |
Sort-Object root -Descending | Out-Gridview
}

I can get it to display the drive information for each server on the list but gridview does not work. I have tried moving the brackets around (before and after gridview) as well as piping elements but have had no luck.

Can anyone advise me as to what I am doing wrong? I feel like it is something simple but all of the examples I am finding online do not use the foreach command which I think has to do with throwing it off.

• Your Select-Object is missing pipeline input - pipe the Invoke-Command call's output to it.

• Instead of -InputObject, use -Property:

  • Note: -InputObject is the parameter that facilitates pipeline input, and is usually not meant to be used directly.

  • As with Sort-Object, -Property is the first positional parameter, so you may omit -Property in the call below.

foreach ($server in Get-Content "path.txt") {
  Invoke-Command -ComputerName $server { Get-PSDrive | Where { $_.Free -gt 0 } } |
    Select-Object -Property usedspace, freespace, root, pscomputername |
    Sort-Object root -Descending |
    Out-Gridview
}

Also note that -ComputerName can accept an array of computer names, which are then queried in parallel, so if you want to query all computers and then call Out-GridView only once, for the results from all targeted computers:

Invoke-Command -ComputerName (Get-Content "path.txt") { 
    Get-PSDrive | Where Free -gt 0 
  } |
  Select-Object -Property usedspace, freespace, root, pscomputername |
  Sort-Object root -Descending |
  Out-Gridview

To group the results by target computer, use
Sort-Object pscomputername, root -Descending

If you'd rather stick with your sequential, target-one-server-at-a-time approach, change from a foreach statement - which cannot be used directly as pipeline input - to a ForEach-Object call, which allows you to pipe to a single Out-GridView call:

Get-Content "path.txt" | 
  ForEach-Object {
    Invoke-Command -ComputerName $_ { Get-PSDrive | Where Free -gt 0 }
  } |  
 Select-Object -Property usedspace, freespace, root, pscomputername |
 Sort-Object root -Descending |
 Out-Gridview
