Application: Command-Line Interface (CLI) Styles
Prior to graphical user interfaces (GUIs), system administrators and operating system users had to use a command-line interface (CLI) to execute system commands. In most of our modern operating systems, the systems administrator still has the ability to use the CLIs to configure system resources, enhance security, and increase system performance. Within these CLIs, there are methods available to output data in different formats, sort data, and search for specific data stored in memory. These CLI methods include the use of pipe and filtering commands to execute system commands to do the following: configure system resources, enhance security, and increase system performance. As a computing professional, you will be better off by understanding the benefits and limitations of CLI styles beforehand, if and when you want to use them.
Read “Command-Line Reference A-Z” and Red Hat Enterprise Virtualization 3.1: Command Line Shell Guide from this week’s Learning Resources. Then research the Walden Library and the Internet for the history and other details about the pipe and filter style of commands.
