Bash Shell Scripting Tutorial for Beginners from Udemy

Linux has a variety of different shells Like Bourne shell (sh), C shell (csh), Korn shell (ksh), TC shell (tcsh), Bourne Again shell (bash). Certainly the most popular shell is “bash”. Bash is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). bash is not only an excellent command line shell, but a scripting language in itself. Shell scripting allows us to use the shell's abilities and to automate a lot of tasks that would otherwise require a lot of commands.

Bash scripting will help you automate routine tasks and save valuable time, whether you're a sys admin, Linux user or software developer. Shell script is much quicker than programming in any other languages.

The goal of this course is to provide you with a working knowledge of Bash scripting. We'll start with the basics, starting from creating our first Bash script and running it. Next you will learn about the bash environment, local variables, conditional statements, functions, loops, case statements, string operations, and coprocesses.
