How can I run this script against multiple sites

Question

I have a new SharePoint deployment we are in the process of upgrading from SP2007 to SP2010. During the visual upgrade a lot of the branding element have been broken and the organisation has a requirement to maintain look and feel as much as possible. I am testing the upgrade process on a Dev server prior to conducting a full migration and upgrade of the live environment.

To fix the UI issues I have been using the following powershell script on the broken sites:

$web = get-spweb <URL goes here>
$web.UIVersion = 3
$web.UIVersionConfigurationEnabled = $true
$web.Update()

This works but I currently have to run the script with a new URL on every broken site I find. Is there any way I can modify the script to accept a list of URLs and modify them all at once?

Answer 1

You can use a text file to get the list of Web URLs, and loop through this list in PowerShell

UPDATED POWERSHELL SNIPPET

Get-Content 'FULL PATH\\FILENAME.txt' | Foreach-Object {
$web = get-spweb $_
$web.UIVersion = 3
$web.UIVersionConfigurationEnabled = $true
$web.Update()
$web.Dispose()
}

Its better to dispose the $web object after the operation is done.

Content of the text file should be URLs of sites in each line

http://site1url
http://site2url
http://site3url

Answer 2

@("url.1", "url.2") | %{
   $web = get-spweb $_
   $web.UIVersion = 3
   $web.UIVersionConfigurationEnabled = $true
   $web.Update()
} 

consider using try/finally in combination with $web.Dispose() if you have many urls...
