Description

Please note: the first lecture(introduction lecture) audio is very low, so please turn up your pc/windows/mac desktop audio to max, so that you can hear the first lecture clearly. Ubuntu Linux BASH shell terminal is used for this course. An introduction course to the typical Unix/Linux Shell Command Basics, meant for beginners, and therefore does not go into advanced details. If you would like an advanced course on this, please let me know.A Unix shell is a command-line interpreter or shell that provides a command line user interface for Unix-like operating systems. The shell is both an interactive command language and a scripting language, and is used by the operating system to control the execution of the system using shell scripts. In computing, a shell is a user interface for access to an operating system's services. In general, operating system shells use either a command-line interface (CLI) or graphical user interface (GUI), depending on a computer's role and particular operation.
