Linux/Unix Administration

Linux and UNIX are open sources operating systems. In this course, you will learn to supervise data, execute commands and administer your Linux and UNIX operating systems.

The increment in installed systems and also incrementing refinement of networks and end users have designed an expanding interest for immensely proficient UNIX and Linux System Administrators, further UNIX and Linux techniques can advance your career in various Information Technology (IT) fields, being software development and software operation and IT security. UNIX and Linux System Administrators develop and maintain mosaic network connectivity, domain name service, web services, database engines, time service, mail handling, printer service, network file service, virtual environments, and system backups. The infrastructure needs UNIX and Linux System Administrators to determine an accomplishment level to supervise such complex network systems.

Linux is a most leading version of UNIX operating system. Linux was constructed seeing UNIX compatibility. Its component list is analogous to that of UNIX.

Linux Operating System, is a freely available, cross-platform operating system depend on Unix that can be installed on Personal Computers, laptops, netbooks, mobile and tablet devices, video game consoles, servers, supercomputers etc.

Linux Operating System has primarily three components

• Kernel: Kernel is the core element of Linux. It is answerable for all extensive action of this operating system. It comprises different modules and it collaborates directly with the prime hardware. Kernel contributes the required abstraction to obscure low-level hardware information to system or application programs.
• System Library: these libraries implement most of the functionalities of the operating system and do not requires kernel module's code access rights.
• System Utility − System Utility programs are answerable to do specialized, individual level tasks.

Following are some of the important features of the Linux Operating System.
• Portable: Portability means software can work on different types of hardware in the same way. Linux kernel and application programs support their installation on any kind of hardware platform.
• Open Source: Linux source code is freely available and it is a community-based development project. Multiple teams work in collaboration to enhance the capability of Linux operating system and it is continuously evolving.
• Multi-User: Linux is a multiuser system means multiple users can access system resources like memory/ ram/ application programs at same time.
• Multiprogramming: Linux is a multiprogramming system means multiple applications can run at the same time.
• Security: Linux provides user security using authentication features like password protection/ controlled access to specific files/ encryption of data.

Flavors of Linux Operating system.

Linux comes in many different aspects. The basic system is as it is, but the look and feel and the subsystems around it are distinct.

Each version is developed by a distinct organization with its own mindset and desires.

Available few versions of Linux versions are as follows:

Ubuntu's ideology is to obscure the complications of the elemental O/S from the user and to hand over maximum accuracy. The most user-friendly version for Linux beginner Unusually, Canonical gives a free server version of Ubuntu for non- commercial use
• Red Hat: The next most popular freely available version Red Hat includes an authoritative desktop GUI depends on Gnome 3 but there are also different twists of it that use various desktops like KDE. It is based on Red Hat's commercial Linux server distro (RHEL).
• Puppy Linux: Small footprint Linux, relevant for old hardware or low specification machines. Can run easily from a USB memory stick or Live CD/DVD. Puppy Linux comprises a full desktop GUI, browser, general purpose tools and minimal applications. Tremendous for old/low specification hardware.
