Write a shell script. The shell script should ask you a multiple choice question, if result is correct it will print "Congratulation, correct answer" otherwise "Wrong answer, the correct answer is b". (You should use case construct and for each option you will echo the desired result). The output of the shell script should be as shown: What is the world best-selling album of all time? a) Dirty Dancing b) Thriller c) The Dark side of the Moon Show that your executable script is working to the instructor! i.e. use chmod command to make your script executable, then type the name of your script to execute.

Write a bash script that accepts aperson’s name as a command-line argument and simply prints out the following greeting: "Good day, <name_entered>! Nice to meet you!", where <name_entered> is a positional parameter (i.e., a command-line argument) passed to the script. If the user does notenter a command-line argument when invoking this shell script, you will simply output: "Hope you have a great day!", without any name displayed. How to do this??

Write a shell script which takes an input (an integer smaller than 10,000) from users and displays each digit of the integer one by one. For example, if you input “153”, the shell script will identify and display “1”, “5” and “3” on the screen sequentially. If you input “69”, it will display “6” and “9”. (Hint: you may use % operator)

Write a shell script that prompts the user for a grade between 0 and 100. The shellscript should calculate the corresponding letter for this grade based on the followingcriteria:0–49 = F50–59 =D60–69 = C70–79= B80–100 = AEnsure that the shell script continues to prompt the user for grades until the userchooses to exit the shell script.
The name of the following shell script is “abc” SEE THE IMAGE 19.1 Please explain what this script does.19.2 Suppose the user runs it $ ./abc. This script prompts the user, and the user enters the following numbers in sequence 4, 8, 0, 4, 2. Given these input values, can you show all the output lines of this running scri
Use the Bash shell for the completion of this project. Develop a shell scripting application that allows the user to perform some advanced mathematical operations: Task 1: Find the even multiples of any number chosen by the user in a given range – the user should specify the multiples of which number they want to print and a minimum and maximum value. The multiples printed should be within the [minimum, maximum] range. For example, if the user choses the number 7 and would like to print all even multiples in the [15, 60] range, the program should print all the even multiples that are bigger than or equal to 15 (minimum), but smaller than or equal to 60 (maximum). The program should keep a count of how many numbers were printed and should output that count, as well as the numbers. The output then, for theexample given, should be 28, 42, 56, and the count should be 3.
Write a shell script to check if the number input by the user is automorphic or not. You must display your name and registration number. [Hint: Automorphic number are numbers if and only if its square ends with the same digits as the number Itself; E.g. 76 = 76 * 76 =5776, 25 = 25 * 25 =625. The numbers 76 and 25 are Automorphic numbers.]
