Can I get Last write time of a file in SharePoint via Powershell?

Question

Is it possible to get when was the last WRITE time of a file in a document library by using Powershell?

Answer 1

Try following

$url = "http://myserver/sites/mysite/shared%20documents/myfile.xlsx"
$web = Get-SPWeb http://myserver/sites/mysite
$file = $web.GetFile($url)
$lastWriteTimestamp = $file.Item["Modified"]

OR

$lastWriteTimestamp =  $file.TimeLastModified
