Copy Users and Groups using SharePoint 2010 Power-shell script

In this case i am maintaining values as ";" seperated values in this script. If we want to maintain data please use list items. It is best approach for workflows also.

http://SP2010:8080/Powershellaction.asmx by using this SharePoint 2010 service we able to find the "RunScript" method for power-shell script.

save this script as "TestScript.ps1" and run this file in SharePoint power-shell cmd prompt. 

>&"c:\TestScript.ps1"

TestScript.ps1:

web = Get-SPWeb "http://SP2010:8080/sites/12345Test2"

for ($i = $web.RoleAssignments.Count -1; $i -ge 0; $i--)

{ 

    $web.RoleAssignments.Remove($i) 

}  

if($web.SiteGroups["Engineers"] -eq $null) 

{

          $web.SiteGroups.Add("Engineers", $web.Site.Owner, $web.Site.Owner, "Use this group to grant people Contribute permissions to the $web site")

}

$EngineersGroup = $web.SiteGroups["Engineers"]

$EngineersGroupAssignment = new-object Microsoft.SharePoint.SPRoleAssignment($EngineersGroup) 

$EngineersGroupRoleDefinition = $web.Site.RootWeb.RoleDefinitions["Contribute"] 

$EngineersGroupAssignment.RoleDefinitionBindings.Add($EngineersGroupRoleDefinition) 

$web.RoleAssignments.Add($EngineersGroupAssignment) 

$EngineersGroup.OnlyAllowMembersViewMembership = $false 

$EngineersGroup.Update()

$EngineersColl = "prasad, narasimha; siva, narayana" 

$EngineersArray = $EngineersColl.Split(";")

foreach($Engineer in $EngineersArray) 

{  

    $user1 = $web.Site.RootWeb.EnsureUser("$Engineer")  

    $EngineersGroup.AddUser($user1) 

}

$EngineersGroup.Update()

$web.Update() 

$web.Dispose()

this script will create two users under the Engineers group.
