Create regular expressions that meet the following criteria. You may use grep or egrep to answer these questions.

1.Display all lines where the employee’s age is greater than 40 years old. Again, don’t think of this as a number, think of it as a series of characters.

Answer 1

grep -E "forty|fifty|sixty|seventy|eighty" lab3test.txt
