In this challenge, you will perform command-line tasks by using shell operators. First, you will determine file attributes by using file test operators, and then you will compare variables by using relational operators. Next, you will perform logical operations by using Boolean operators, and then you will perform arithmetic operations on operands by using arithmetic operators. Finally, you will create a search utility by using a script. Note: Once you begin the challenge, you will not be able to pause, save, or return to your challenge. Please ensure that you have set aside enough time to complete the challenge before you start.
