how to use grep to filter out rows that contain dates that are before a certain day


Vote count:

I have a sample employee data file, and I want to filter out the rows where the Employement_Status column is INACTIVE and the Hire_Date is before 2013 June 1st.


The rows in the file look like this



FirstName LastName BirthDate EmploymentStatus HireDate
Tom Red 5/16/1956 INACTIVE 4/13/1999
Sandy Green 12/21/1973 INACTIVE 12/20/2013
John Yellow 11/15/1983 ACTIVE 8/17/2000


And the grep command should only remove the second row.


Thank you very much
