Although you need to study concepts throughout this course, you will also need to learn to get '''issue simple as well as more advanced practice running Linux commands'''. This requires that you practice issuing Linux commands on a frequent basis to become more comfortable when working within the '''Unix''' and '''Linux command-line environments'''.
For this course, it is important to learn how to '''open a command prompt in order to issue commands to perform common tasks'''. In Unix/Linux, a '''shell''' is simply an interface / interpreter to allow a user to communicate with the Linux computer system (server). Linux shells have evolved (improved) over a period of time. You will be using the '''Bash Shell''' which is considered to be user-friendly. By understanding how to issue Linux commands, you can create a file that contains Linux commands (called a '''shell script''') to automate tasks to make you a more '''productive''' user and administrator.
