Write a script that outputs all lines in a file containing a specific keyword. Your script will be called fkey and the first argument to the script should be the keyword and the second the file i.e. the general form of the command should be $ fkey keyword filename For example, if the users types: $ fkey apple foo.txt your script should print every line that contain the string apple from the file foo.txt. A test file foo.txt is attached. In addition, you must check if the user specified two arguments. If not, you will print the following error message: usage: fkey keyword filename You must also check if the second argument is a file that exists. If it doesnt, the script will exit and print an error message stating that the file does not exist.

I like apples. I like blueberries. I like pineapples and strawberries. Apples are tasty. Bananas are sweet
