Shell scripting involves writing a series of command for the shell to execute. It combines lengthy and repetitive sequences of commands into a single script, which can be stored and executed anytime. This reduces the effort required by the end user and the number of human mistakes. You will write your first shell script and delve into the shell, to touch the power CLI which provides against the GUI. Also you will learn simple arguments and use getopts to make it a real Shell command. Then you will learn looping and functions for performing complex operations. You will then master Regex and regular expressions to validate your arguments. Finally, you will learn to write logs correctly and fight the temptation to use I/O redirections. By the end of this course, you will be an expert at creating powerful shell scripts and will have explored the full possibilities of shells.
