Who will benefit from this course? This course is valuable for those interested in acquiring a comprehensive foundation knowledge in the Linux operating system. This course is the first step in becoming a Linux administrator, developer, security specialist, application support specialist, and more! What background do I need? Previous experience with Linux is not required for this course. Familiarity operating a computer system and basic computer knowledge is assumed. What is Linux? Linux is an open-source operating system, available for free by downloading over the Internet, that can be used to implement a high-performance, stable and inexpensive server. There are many Linux distributions available, however all of them usually contain the same wide variety of GNU and other open-source tools for all types of users and administrators. These tools include: Office productivity tools: word processors, spread sheets, etc. Programming tools: compilers and various programming languages Internet tools: Web browsers, FTP clients, chat clients System tools: Graphical user interface (GUI) administrator tools to perform common tasks, shells, system monitors Graphics tools: image editors and viewers How does Linux relate to UNIX? Both UNIX and Linux are very similar in function and both attempt to conform to what is known as the POSIX standard for operating systems. UNIX is well known for its enterprise features of stability, security and scalability, however it is typically run on very expensive server hardware and sold only by a few large vendors. Linux contains the same enterprise features as UNIX but, due to its open-source nature, is available in many distributions for many different hardware platforms including less expensive PC-based systems. What is a Linux distribution? A Linux distribution refers simply to an individual vendor's version of Linux. Linux, to be accurate in terminology, refers to the kernel, or core of the Linux operating system. Administrative commands, applications, servers, etc., are provided by various organizations in the open-source community. A distribution contains the Linux kernel plus a set of GNU utilities, various network servers and graphical environments. There are many distributions available, from larger organizations like Sun and IBM, to a wide-range of popular distributions from Red Hat, SUSE, Debian, Mandriva, etc. What distribution of Linux is used on this course? This course uses Red Hat Enterprise Linux. However, the focus of this course is foundational and concentrates on those aspects of Linux that do not vary much between Linux distributions. The concepts taught in this course are applicable to all Linux distributions. How much time is spent on each topic? Content Hours Introducing Linux 1.0 Accessing the system 2.5 Managing files and directories 4.5 Controlling access to Linux resources 3.0 Searching the system 1.5 Manipulating text files and streams 3.0 Leveraging Bash shell features 2.0 Automating tasks with shell scripts 2.0 Executing jobs and processes 1.0 Archiving and retrieving data 1.0 Times, including the workshops, are estimates; exact times may vary according to the needs of each class. How much time is spent on hands-on exercises? A substantial amount of time on the course is devoted to hands-on exercises, allowing you to develop your skills on Linux. Exercises include: Accessing graphical applications from the GNOME desktop Setting and testing file permissions Formatting and changing text using filters and pipelines Writing and running shell scripts to automate tasks Creating and executing compressed archives And much more! Will I learn to work with the command line and graphical tools? Yes! A major focus of this course is on command line tools for this is where the real power for automation in Linux lies. You will gain hands-on experience working in a graphical user interface (GUI) to access many graphical tools and explore file management using Nautilus, the Linux file manager. Will I learn to install and configure a Linux distribution? No. This course focuses on the basic skills any administrator would need to manage a Linux system. The skills learned on this course are a springboard to Course 144, Linux® Administration and Support: Hands-On, where you will perform a full Linux installation and configuration.
