Basic Linux Shell Scripting Language - PART II



Also Read: 
In the previous article on Linux Shell Scripting Language, we had already covered following points:
  • What is a Shell?
  • Types of Linux Shell- Bourne Shell, C Shell, Korn Shell and the BASH Shell (Bourne Again Shell).
  • Shell Programming - The Basics
  • Writing the First Shell Script - Hello World
 In this article, we would write some more basic shell scripts that will give you much more comfort while writing more complex scripts. Please note that, this article is an extension of my previous article "Getting Started - Linux Shell Scripting Language".
So, without much a do, lets start the show.

1. Fun with the $USER

In the first script of this article, we will make use of the shell variable $USER. It stores the information about active user of the system. Just observe the following script that displays IP Address Details to its user.

Input:
Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Output:

Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting, Linux Shell Scripting,


    Remember, whenever you try to create a script, it should have an extension .sh and make it executable before you run it.

    Script is nothing but a number of commands pipelined together. Shell Scripts are just great for concise file-system operations. When you need Better functionality,  better robustness, better performance and better efficiency then you may adopt a more full-featured language.

    If you are acquainted with programming languages like C or Python or Perl, then you can learn Shell Scripting with much more comfort.

2. An Interactive Script

    In the second script of this article, we expect the user to take part in the communication. This script will take texts from the user, save it in some variables and using those variables, something is displayed back on the screen for the user.

For Example,
echo -e "\033[32m Your Own Linux...!"

6. Email Alert!

Time to create a script that will send you an email when disk utilization exceeds some pre-determined threshold. If you are a web administrator, then this script will prove to be pretty essential for you. Check out the script:


    You need to make a few changes in the script, replace the field 'USERNAME@domain.com' with your Email ID and it's done.

    That's all for this article! There are no boundaries when it comes to writing scripts and programming stuffs, you can create as many scripts as you want. If you like this article or you have some suggestions, fell free to comment and stay tuned for some more articles on Linux Shell Scripting Language. Happy Scripting!
