Find share sizes across multiple servers -powershell - powershell

Question

I have about 1600 old home drives that I need to capture the folder sizes on. They are spread across 12 NAS Appliances and I need to get the size of each folder. I see this asked a lot but they are always asking for all the shares on a single server.
I have used simple one-liners like the the one below which work great.
Get-ChildItem \\Server1\Users\User1 -file -recurse | Measure-Object -Sum Length
How can I feed in a txt or csv from multiple locations?
Like
\\Server1\Users\User1
\\Server2\Users\User1
\\Server3\Users\User1
\\Server4\Users\User1
\\Server5\Users\User1
\\Server6\Users\User1
\\Server7\Users\User1
etc...
Exporting to a csv would be nice as well.
thanks!!

You can use Get-Content to read your text file line-by-line:
Get-Content .\path\to\file.txt
Next up we need to repeat your one-liner for each line:
Get-Content .\path\to\file.txt |ForEach-Object {
Get-ChildItem $_ -File -Recurse | Measure-Object -Sum Length
}
This will give us 1600 individual measurements - but now we won't know which paths they belong to...
To track which measurement belongs to which user directory, let's create a new object containing both all the information instead:
Get-Content .\path\to\file.txt |ForEach-Object {
$Measurement = Get-ChildItem $_ -File -Recurse | Measure-Object -Sum Length
[pscustomobject]#{
Path = $_
FileCount = $Measurement.Count
TotalSize = $Measurement.Sum
}
}
Finally, we can export to CSV using Export-Csv:
Get-Content .\path\to\file.txt |ForEach-Object {
$Measurement = Get-ChildItem $_ -File -Recurse | Measure-Object -Sum Length
[pscustomobject]#{
Path = $_
FileCount = $Measurement.Count
TotalSize = $Measurement.Sum
}
} |Export-Csv .\path\to\output.csv -NoTypeInformation
