Question

Create a shell script called (Main.sh). The script must call the following scripts (FileS.sh), (Work.sh), (Ether.sh), (Arch.sh) and (Buzz.sh). The first script Main.sh must have two subroutines.

The First Subroutine will display the following messages on the screen:

1-Display User login name, date and time.

2-Display System boot time.

3-Working path and Shell type

4-Display Home directory and number of files and directories in your Home.

5-Message describing briefly the requited tasks.

Answer 1

Please find below the solution to your question, also find the screenshot of the output which I got after running this code.
1. subroutine1 covers the all 5 points mentioned in the question
2. subroutine2 calling to other scripts(correct the file path as per your file location)

#!/bin/sh
subroutine1()
{
        #echo "Arg 1: $1"
        echo "user Login Name : $(echo $USER)"
        echo "Current date and time : $(date)"
        echo "System Boot Time:" 
        who -b
        echo "Current Working Path:"; pwd
        echo "Shell Type:" $SHELL
        echo "*******************************************"
        echo "Home Directroy:" $HOME
        echo "Number of files and directories in home:"
        #sudo apt install tree ( if you haven't already installed in your system)
        tree $HOME | tail -1
       echo "*******************************************"
}
subroutine2()
{
        echo "inside subroutine2"
    #correct the file path as per your file location.
        /home/abhishek/Downloads/FileS.sh
        /path/to/files/Work.sh
        /path/to/files/Ether.sh
        /path/to/files/Arch.sh
        /path/to/files/Buzz.sh
}
subroutine1 
subroutine2

output:
(I havent specify the file path therfore in screenshot you are seeing error file not found) but It is worked fine for FileS.sh as I have mentioned It's path in the script.
