Linux System Administration

What is Linux?

  • In general, Linux implies rather just a Kernel than a whole OS.

  • Linux OS distributions include
    generic or customized Kernel and
    generic or customized GNU software (libraries, shells, and applications).
  • This is why the operating system is correctly called GNU/Linux, and commonly refered as "Linux".

  • Source codes of the Kernel, shells and GNU applications are freely available to anyone.

  • Traditional tools for Linux administration and development:
         C - programming language
         Shell scripting
