Get List of all SharePoint GUIDs using PowerShell
Below are the scripts that can help you retrivesharepoint GUIDs which at times are very handy.
Lets start with Sharepoint 2010
$site = Get-SPSite http://yourserver/sites/yoursite
$web = $site.OpenWeb("yoursubsite")
write-host "Site: " + $site.idwrite-host "Web: " + $web.id
$web.lists Format-Table title,id -AutoSize$web.Dispose()
$site.Dispose()
Quick Trick Note: You could change $site.OpenWeb("yoursubsite") to $site.RootWeb to get just the top site.
Now lets take SharePoint 2007
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")
$site = New-Object Microsoft.SharePoint.SPSite("http://yourserver/sites/yoursite")
$web = $site.OpenWeb("yoursubsite")
write-host "Site: " + $site.idwrite-host "Web: " + $web.id
$web.lists Format-Table title,id -AutoSize
$web.Dispose()
$site.Dispose()
Hope this helps
