Unix is an operating system that uses a command-line interface. A free and widely popular version called Linux uses the same commands as Unix. Both operating systems use shell scripts, or scripts written for a command-line interpreter, to run applications and programs. When using Unix, you will need to know the particular commands and switches that run applications on the operating system. Performing tasks like unzipping multiple files is less intuitive than in a graphical operating system, so knowing the particular techniques to do so can be very useful.
