→USING YOUR MATRIX ACCOUNT
In Unix/Linux, a '''shell''' is simply an '''interface''' 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''') later in this course to automate tasks to make you a more '''productive''' Linux user and system administrator.
