PowerShell-based Windows version of "stat"

Unix-like OSes have a "stat" command that produces certain interesting information on a file system object. One questioner was wondering what the Windows equivalent is. I don't believe there's a single command to produce all that, but I did put together a PowerShell script:

$obj = $args[0]
If ($obj.GetType().Name -eq 'String') {$obj = gi $obj}
'File: ' + $obj.FullName
'Size: ' + $obj.Length
$extents = [string](fsutil file queryextents "$($obj.FullName)")
If (-$extents.StartsWith('i')) {
  'Clusters: ' + ($extents.Substring(26) -split 'LCN')[0]
  'LCN: ' + $extents.Substring(42)
} Else {
  'Clusters: stored in file table'
}
'Attributes: ' + $obj.Attributes
$volumeinfo = (fsutil fsinfo volumeinfo "$([System.IO.Path]::GetPathRoot($obj.FullName)[0] + ':')")
$volumeinfo | ? {$_.StartsWith('Volume Serial')} | % {$_.Replace(' :', ':')}
$fileid = (fsutil file queryfileid "$($obj.FullName)")
'File ID: ' + $fileid.Substring(11)
$links = (fsutil hardlink list "$($obj.FullName)")
'Links: ' + ([string[]]$links).Length
'Owner: ' + $obj.GetAccessControl().Owner
''
'Access: ' + $obj.LastAccessTime
'Modify: ' + $obj.LastWriteTime
'Create: ' + $obj.CreationTime
'' # Extra blank line for readability
