Although you need to study concepts throughout this course, you will also need to learn to '''issue and memorize simple as well as more advanced 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'''.
Just like with other operating systems like MS WindowsFor 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 consisting of Linux commands and programming techniques called a '''shell script''' (learned later in this course) to automate tasks to make you a more '''productive ''' user and administrator.
