In operating system
refers to directing input
other than the default I/O
devices. By default, input generally comes from the keyboard
, and output goes to the display monitor
. With a redirection operator
, you can override these defaults so that a command
takes input from some other device and sends output to a different device.
In DOS and UNIX systems, the redirection operators are for input and > for output. For example, the DOS command
takes input from a file called list, sorts it, and sends output to a file called sorted.
