I want to write a trigger to insert a feed in chatter which could be a link to the library when I create a content in a library.{ Link to the content in the library preferably .But even a link to the library will do}

trigger ContentVersionTrigger on ContentVersion (after insert) 
{ 
   ContentVersion[] cv=Trigger.new; 
   InsertToChatter.InsertContent(cv); 
} 


public class InsertToChatter
{ 
   public static void Insertcontent (ContentVersion[] cv) 
   { 
     FeedItem post = new FeedItem(); post.Body = 'New file has been created.Pls check link'; 
     post.LinkUrl= URL('cs18.salesforce.com/sfc/#version?selectedDocumentId='+ cv.ContentDocumentId' ;
     insert post; 
    } 
}

Possible Suggestion/Solution #1

You can do this by creating a trigger on ContentDocument SObject on after insert event to get the Id of the document and create a FeedItem record with a link to your ContentDocument (/sfc/#version?selectedDocumentId=yourDocumentId)

Give it a try and post your code here if you need help with it

I have tried writting trigger on ContentDocument. It is working as of now..

Here it is the code :-

trigger PublishlinkOnChatter on ContentDocument (After insert,After Update) {
    list<FeedItem> lst=new List<feedItem>();
    for(ContentDocument cd:trigger.new){
            FeedItem fi= new FeedItem();
            fi.LinkUrl='https://na15.salesforce.com/'+cd.LatestPublishedVersionId;
            fi.parentid=userinfo.getUserID();
            fi.body='Modified the Content';
            lst.add(fi);


        }
        insert lst;
}
