Input and output redirection

The AIX® operating system allows you to manipulate the input and output (I/O) of data to and from your system by using specific I/O commands and symbols.

You can control input by specifying the location from which to gather data. For example, you can specify to read input while data is entered on the keyboard (standard input) or to read input from a file. You can control output by specifying where to display or store data. You can specify to write output data to the screen (standard output) or to write it to a file.

Because AIX is a multitasking operating system, it is designed to handle processes in combination with each other.
