This lesson will cover a small number of basic commands. This lesson uses a Unix shell, which is a command-line interpreter that provides a user interface for the Unix operating system and for Unix-like systems. This tutorial provides a basic introduction to the bash terminal, and Windows users can follow along by installing popular shells such as Cygwin or Git Bash (see below). On OS X or many Linux installations, the shell is known as bash, or the ‘Bourne-again shell.’ For users on Windows-based systems, the command-line interface is by default MS-DOS-based, which uses different commands and syntax, but can often achieve similar tasks.
There are two main command-line interfaces, or ‘shells,’ that many digital historians use. Furthermore, they can be easily automated through scripts, which are essentially recipes of text-based commands. They allow for more detail when running some programs, as you can add modifiers to specify exactly how you want your program to run. Before the rise of GUIs in the late 1980s, however, the primary way to interact with a computer was through a command-line interface.Ĭommand-line interfaces have advantages for computer users who need more precision in their work – such as digital historians. This means that when you go into a folder, you click on a picture of a file folder when you run a program, you click on it and when you browse the web, you use your mouse to interact with various elements on a webpage. The usual way that computer users today interact with their system is through a Graphical-User Interface, or GUI. Many of the lessons at the Programming Historian require you to enter commands through a Command-Line Interface.
