In LINUX, three files are automatically opened by the kernel for every command for the command to read input from, and send its output and error messages to. These files are known as standard files: standard input (stdin), standard output (stdout), and standard error (stderr). By default, these files are associated with the terminal on which the command executes. More specifically, the keyboard is standard input and the display screen (or the console at which you are logged in) is standard output and standard error. Therefore every command, by default, takes its input from the keyboard, and sends its output and error messages to the display screen (or the console window).
