Write a shell script that does the following: The Script should accept an integer value as a command-line argument. At first, a greeting message should be displayed Hello, username. Your current working directory is path Where username is your ubuntu user name and path is the path of your current working directory. (use the appropriate Linux commands to do that) Then a menu should be displayed that has the following list of options ( 4 options ): 1- Arrange my Files. Prompt the user to enter a directory name and create it. Then move all the (.cpp) files to the created directory. Hint: use my *.cpp command to do that 2- Check my Number Check if the number passed as command argument is divisible by 7 or not. If no command-line argument passed, it should display the message No number found. 3- Search my directory. Prompt the user to enter a directory name and a word (pattern), then list all the files in that directory that has this word. Hint: use grep command with -r and -c option. 4- Exit To exit the script If the user enters a number not in the list of options, then an appropriate message should be displayed. Sample Input/output: hoortya@ubuntu:-$ bash myscript.sh 21 Hello, hoortya Your current working directory is /home/hoortya please choose one of the following: 1- Arrange my files. 2- Check my number. 3- Search my Directory. 4- exit. 3 enter a searching word fork enter a directory name diri dir1/t4.cpp:2 dir1/t3.cpp:0 dir1/t1.cpp:1 hoortya@ubuntu:~$
