​If you are looking to script the unfollowing of the sites in SP 2013 then you can use the following PowerShell. You can loop through users to execute the following code. For this sample I have hard coded User Name and Site URL.

$userName = "Contoso\brianc" 

$site = Get-SPSite "http://intranet.contoso.com"

$serviceContext = Get-SPServiceContext($site)

$profileManager = new-object Microsoft.Office.Server.UserProfiles.UserProfileManager($serviceContext)

if($profileManager.UserExists($userName))
{
     $userProfile = $profileManager.GetUserProfile($userName)
    
     $followingManager = new-object Microsoft.Office.Server.Social.SPSocialFollowingManager($userProfile, $serviceContext)
     
     $followed = $followingManager.GetFollowed("Sites")
     
    $actorInfo = new-object Microsoft.Office.Server.Social.SPSocialActorInfo
    
     foreach($site in $followed)
    {        
        $actorInfo.ContentUri = $site.Uri
        $actorInfo.AccountName = $userProfile.AccountName
        $actorInfo.ActorType = "Site"
        $followingManager.StopFollowing($actorInfo)
    }

}​

Sometimes when adding an item to your list or library you may want some of the metadata have default value selected. Today I am going to provide a quick tip on how you can set your Year column (textbox or dropdown) defaulted to current year value using Jquery.

<script language=”javascript” type=”text/javascript” 

src=”/Style Library/jquery-1.9.0.min.js”></script>

    <script language=”javascript” type=”text/javascript”>
    $(document).ready(function() {
     
    var currentYear = (new Date).getFullYear();

    // For Textbox  (change title value to your column title)
   
    $(“input[Title=’Year’]”).val(currentYear);
   
    // For dropdown(change title value to your column title)
   
    $(“select[Title=’Year’]”).val(currentYear).attr(“selected”, “selected”);
     
    });
</script>

This question comes up quite often. If you are building a SharePoint workflow (either Sequential or StateMachine) using Visual Studio 2010 and if you sometime want to check the status of your task using code then you can simply use the following code to achieve that.

TaskAfterProperties.ExtendedProperties
                    [SPBuiltInFieldId.TaskStatus].ToString()

The above code runs OnTaskChange Activity and uses Task AfterProperteis to get the Task Status.

Pretty Simple !!!

​Microsoft have published a great article on PowerShell for SP2013 learning roadmap. You can go to the article by clicking the image below.

I would highly recommend this article to anyone who is new to SharePoint and wants to learn PowerShell.

Cheers.
