asked on

Could anyone write me a powershell script that does the following...?

All our users' home folders are located on the file sevrer, in E:\Folder\%USERNAME%\. Inside this is a folder called Flags. What I want is a PowerShell script that created an empty file E:\Folder\%USERNAME%\Flags\Pin2016.flg - recursively for every user E:\Folder\%USERNAME%

It's PowerShell Version 4 on Windows Server 2008 R2

Also it would be good to have the result for each file creation dumped to a log file, because there might be one or two Flags folders in there that has weird permissions.

Thank you.

Try this; it's in test mode and will not actually create the files. Remove the -WhatIf in line 8 to run it for real.

$FileName = 'Pin2016.flg'
$LogFile = 'C:\Temp\FlagFileCreate.csv'
Get-ChildItem -Directory -Path C:\Temp |
	Where-Object {Get-Item -Path "$($_.FullName)\Flags" -ErrorAction SilentlyContinue} |
	ForEach-Object {
		$Return = $_ | Select-Object -Property @{n='Path'; e={$_.FullName}}, 'Result'
		Try {
			New-Item -Path "$($_.FullName)\Flags" -Name $FileName -ItemType File -ErrorAction Stop -WhatIf | Out-Null
			$Return.Result = 'OK'
		} Catch {
			$Return.Result = $_.Exception.Message
		}
		$Return
	} | Export-Csv -NoTypeInformation -Path $LogFile

If you do not need a sophisticated analysis of failures, a simple brute-force approach is best:

set-location E:\Folder
Get-ChildItem -recurse -filter flags -Directory | % {
  try {  "" | Set-Content "$($_.FullName)\Pin2016.flg -force }
  catch { "The flag in $($_.FullName) could not be created" | Add-Content flaglog.txt }
}

Open in new window

This will, of course, overwrite existing flags. Adding a test for existence is easy:

set-location E:\Folder
Get-ChildItem -recurse -filter flags -Directory | 
  ? { !(Test-Path "$($_.FullName)\Pin2016.flg") } |
  % {
  try {  "" | Set-Content "$($_.FullName)\Pin2016.flg -force }
  catch { "The flag in $($_.FullName) could not be created" | Add-Content flaglog.txt }
}

Thank you both.

Qlemo, I'm getting...

Also, I think both of the scripts are written to... "Find a 'Flags' folder, then create a file inside it", but this doesn't catch the user folders where the folder doesn't exist, e.g. if it's been deleted by the user. Could you adjust it so that it just goes through all the folders within E:\Folder, then creates file Flags\Pin2016.flg inside each one? Then the log file would report on the file creation success according to each user folders, rather than each Flags folder.

Thanks.

That does exactly what I need. Thanks.

Sorry, I've found something in the script that I'd like to adjust. Would you mind having the script add Full Control permissions to the Everyone group to the file as it's created?

Thank you very much.
