Create a script called q$04.$sh that accepts a filename as a command$-$line parameter $($i$.$e$.,$ argument$).$ When run, the script will request the user to enter a word at the terminal $($command line user input$).$ After the input, the program should return the number of occurrences of the word within the file given by the command line parameter. The program will not stop asking for a word and returning the number of occurrences until it encounters an empty terminal user input. Make sure that the script can be run as follows:

$./$q$04.$sh story.txt $($ searches the file story.txt for each of the words as specified by user command line input $)$

and produces the number of occurrences of each word given $($one number per line$).$ You should provide a prompt message asking the user to enter the word.

When you have completed the script answer the following questions:

Enter the word DONE in part A when you have finished your script.

How many times does the whole word happy appear in the file story.txt$?$

How many times does the word unhappy appear in the file story.txt$?$

Can you accurately predict, based on the number of times the word murder appears in the file story.txt and the number of times the word love appears in story.txt$,$ whether story.txt contains a murder mystery or a love story? $($Enter Yes or No for your answer$)$

Enter your answers in q$04/$a$04.$txt$.$
