Bash Shell Scripting in Linux - The Urban Penguin

LEARN SHELL SCRIPTING WITH BASH

Beginning Programming by Shell Scripting with BASH

Welcome to this mini-series of video tutorials where we look to assist you in shell scripting using the BASH shell. Shell Scripting of any variety is often the first journey in becoming a programmer. Starting with BASH shell scripts you can quickly move onto other scripting languages such as Python or Perl before moving into Java or C.

Firstly we will start with the basics of creating and debugging scripts before moving onto IF statements, CASE statements, flow control with loops and all that you may want to do to get started with scripting with /bin/bash. Fearing the shell is not something you should ever concern yourself with so if you do not understand some of these terms right now you will later. For the moment all that we would expect is that you can access the command line on Linux and know some basic commands.
