PowerShell Cmdlets Recursiveness: Why use Get-ChildItem? Yes, this example PowerShell script can use a lot of memory when run on a directory with millions of files. When we’ve found a match ( if ( $f.Owner -eq $username )), the result is written to our logfile with Write-Host and a piped Out-File. The file (or folder) path itself is stored in.

We only want the files owned by the specified user, for which we use the Owner property. Within our PowerShell Foreach loop, the Get-Acl Cmdlet is used to retrieve the ACL’s, or Access Control Lists, of that file or directory. The result – all files – is stored into the $path variable, through which we loop with Foreach. Since we want to find all files, we recurse into subdirectories using the -Recurse parameter.

The specified location is the current directory: '.'. The Cmdlet Get-ChildItem is used to get the items and child items (folders and files) in a specified location. And we define a path for our results logfile with $outfile. First we define a $username to search for, which can be either an AD user or local user. What the above PowerShell script -to find all files owned by a particular user- does is pretty straightforward. Find files owned by a user – script explanation The Windows PowerShell runtime also invokes them programmatically through Windows PowerShell APIs. The Windows PowerShell runtime invokes these cmdlets within the context of automation scripts that are provided at the command line. A cmdlet is a lightweight command that is used in the Windows PowerShell environment. PowerShell CmdletsĬmdlets are the heart-and-soul of Windows PowerShell. Some reformatting was done in this code snippet.
