Hey,

The FILTER operator is used to select the required tuples from a relation based on 'condition'

Suppose you have a .txt file and have loaded the file in Pig. Now using FILTER operator we will get the details of that particular file with given condition.

grunt> file_name = FILTER student_details BY city == 'Banglore';

Here, based on condition we will get students details who lives in Banglore.
