دوره آموزش RedHat Linux

 In this course, we cover the main aspects of the Bash shell, still the most popular Linux command shell. Throughout the course, the author uses a balance of theory and practical examples to teach the fundamental components of the Bash shell. This is not a course that teaches hundreds of commands and shortcuts, it's a course that gets under the covers of the shell and demystifies the inner workings so that learners have a solid foundation to build on. Throughout the course, all theoretical principles are backed up with hands-on examples.
