LX102: Introduction to Linux for Developers (2 Days)
Course Overview
This course provides an introduction to Linux for Developers. It provides an overview of the main
features of Linux that are applicable to developers including: installation and configuration, kernel
overview, understanding Linux file systems, run-level services, using and writing BASH/Python scripts,
package management, processing command-line and environment variables, error handling, file handling,
processes and threads, signals, inter-process communication (including pipes, named pipes, and shared
memory), console applications, GUI applications, and web applications.
The formal course examples and exercises will be based around the Fedora Core distribution of Linux
but differences to Redhat and other distributions will be noted when possible.
