2. 2. Making Bash Shell Script

   Then to Create a Bash Script on Home Directory with nano
   First, Change to the User’s Home directory with:

   cd ~

   Then to Make the Bash Script with nano play:

   nano mybashscript.sh

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

   #!/bin/bash

   Then for our Testing pourpose we Append something like a classic Hello-Word greating:

   echo 'Hello World!'

   And the ‘echo‘ Bash Command simply Output a String on Terminal.
   Finally, our simple Bash Script is containing just:

   #!/bin/bash
   date/necho 'Hello World!'/necho 'From the Bash Shell'
   

   The Bash Commands must be in a Stack of sigle Commands like:

   myBashCommand1
   myBashCommand2
   ...

   myBashCommand1 ; myBashCommand2 ...
