The text already visible inside the program window is called a prompt. By typing various commands at the prompt, you can control the operating system. Most commands accept options and arguments. An option , sometimes called a switch, modifies the way a command works. It usually consists of a single character prefixed with a dash. An argument tells the command which files, directories, or other targets a command should operate on. You can use the arrow keys and delete keys to correct typing mistakes. Press Enter to execute your command.
