The MORE Filter

DOS uses elements called filters to channel information between devices. You can use these filters to modify information as it passes from files to the screen. Filters, which work only on ASCII text files, are often used with the redirection symbols so that input can come from a source other than the keyboard or be sent to a device other than the screen.

Piping is another feature used with these commands. You use the pipe symbol (|) to send output information that normally goes to the screen as input to another program. Piping, a form of redirection, diverts information destined for a device but then makes the information become the input from a device to another program.
