Answer 1

If you want to write the distinct result in a file using javascript...this is how you do

cursor = db.myColl.find({'fieldName':'fieldValue'})

var Arr = new Array();
var count = 0;

cursor.forEach(

function(x) {

    var temp = x.id;    
var index = Arr.indexOf(temp);      
if(index==-1)
   {
     printjson(x.id);
     Arr[count] = temp;
         count++;
   }
})
