LPI Linux Certification in a Nutshell, 2nd Edition

Chapter 5. GNU and Unix Commands (Topic 1.103)

This Topic covers the essential aspect of working interactively with Linux command-line utilities. While it's true that GUI tools are available to manage just about everything on a Linux system, a firm understanding of command-line utilities is required to better prepare you to work on any LSB-compliant Linux distribution.

The family of commands that are part of Linux and Unix systems has a long history. Individuals or groups that needed specific tools contributed many of the commands in the early days of Unix development. Those that were popular became part of the system and accepted as default tools under the Unix umbrella. Today, Linux systems carry new, often more powerful GNU versions of these historical commands, which are covered in LPI Topic 1.103.
