Making Script

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
   echo 'Hello World!'
   echo 'From the Bash Shell'
   

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

   myBashCommand1
   myBashCommand2
   ...
   

   Or otherwise in a Line of Commands Divided by a ‘;’ SemiColon as:

   myBashCommand1 ; myBashCommand2 ...

   Ctrl+Shift+v to Paste content into nano.
   Use Ctrl+x to Save & Exit from nano Editor.
