Although you need to study concepts throughout this course, you will also need to get '''practice running Linux commands'''. <br>This requires that you practice issuing Linux commands on a frequent regular basis to become more until comfortable when working within in the '''Unix''' and '''Linux command-line environments'''environment.
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.
