Learn . how to use I/O redirection in UNIX to redirect input from a file and output to a file.. Overview of I/O Streams . To bring in information, a program opens a . stream. on an information source (a file, memory, a socket) and reads the information sequentially, as shown in the following figure. . CSC215. Lecture.
