- Part 2 Write a shell script that accepts two arguments. The first is a string, the second is a file name. The script searches the file for the string, then it displays one of these messages. 1. If the string is in the file, it should display "word does exist in file_name", where word is the string that is the first command line argument, and file_name is the name of the file given in the command line arguments 2. If the string is not in the file, it should display "word does not exist in file_name", where word is the string that is the first command line argument, and file_name is the name of the file given in the command line arguments 3. If the file does not exist, it should display "file_name does not exist" where file_name is as explained aboveYou develop a Python application for your school.
