Out-gridview does not sorting results - powershell

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
