  • Basic knowledge of computer operations

This is a beginner's guide to Bash Shell Commands. The course can also serve as a refresher for intermediate/Advance level as well. The concepts are explained in depth with example. 

I have ensured to provide a fundamental platform to the students so that they have basic working knowledge of Linux commands which can be honed for furthering once career in the field of Bash and Automation. I tried to quote multiple ways things can be handled so that students can learn and recognize most of the code written by other developers and also pick some of these methods as their best practice.

Through the medium of this course I would like to guide students on the following topics:-

A) Directory structure in Linux
B) Different linux command line
C) Date and calendar
D) Changing the ownership and mode of a file using chmod and chown
E) Process status using top and ps
F) Pipes and redirection
G) File Handling and user input processing
H) Different types of conditional and loop statement in Shell script.
