  2. Editing a Bash Script on Home Directory with nano
    First we Change to our Home with

    cd ~

    Then we Make the Bash Script with

    To be Runnable directly as a Shell Script we append a Bash Shebang to the Top like

    #!/bin/bash

    Then for Testing the Execution we should Insert a classic Hello-Word greating

    echo 'Hello World'

    The ‘echo‘ Command simply Output a String on Terminal
    So finally our simple Bash Script will be containing just

    #!/bin/bash
    date
    echo 'Hello World!'
    echo 'From a Bash Shell Script :)'
    

    The Sequence of Bash Commands must be a Stack of sigle Commands

    myBashCommand1
    myBashCommand2
    ...
    

    Or simply in a Line of Commands Divided by a ‘;’ SemiColon

    myBashCommand1 ; myBashCommand2 ...

    Ctrl+x to Save & Exit from nano Editor

  3. Executing the Hello-World Bash Script
    We Need to give the Execution Permissions with

    chmod +x ./mybashscript.sh

    Then to Run our little Bash Script simply

    ./mybashscript.sh

    You’ll be nicely greeted on Shell with something like
