Class Notes

  1. Introduction
    1. Linux was created by Linus Torvalds between 1991 and 1994
    2. Linux is not a version of Unix
  2. Distributions
    1. Once Linux was released to the public numerous institutions created their own versions of the operating system.  These different versions are called Distributions, or Distros.  Different Distros have different functionality.
  3. Open Source software is not necessarily free software
    1. Make sure you understand the licensing requirements for your Open Source software before you release it into a Production Environment.
  4. Defining The Shell
    1. The Shell is the interface you use to interact with the Operating System.  Windows uses a GUI (Graphical User Interface) Shell, Linux primarily uses a LUI (Line User Interface)
  5. ROOT
    1. ROOT is the highest level of anything in the Linux world.  ROOT user is the highest level user.  The ROOT directory s the highest level directory.
  6. Capitalization matters in Linux (HOME is different then home)
  7. Server vs. Desktop Versions
    1. Server versions of Linux install the bare minimum number of components for the system to function.  After installation you will be faced with a blinking cursor.
    2. Desktop versions of Linux come prepackaged with a GUI environment and numerous tools and applications. After installation you will be presented with an environment that looks a lot like Windows or the Mac OS.
  8. What Linux is really god for?
    1. Linux is great for server functionality
    2. Linux is still poor for every day desktop functionality for most users.

    Great thanks.

    Great intro, however you completely ignored the contributions of GNU. The reality is that Linux is just the kernel, not the Operating System. In fact, the OS is GNU. You give ALL of the credit to Linus Torvalds and you don’t even mention GNU. Please read up on the facts and educate yourself regarding GNU/Linux. http://www.gnu.org/gnu/linux-and-gnu.html

    Sir you are really the best. I have recently finished my MPhil degree course in P2P networks from one of a University in UK. These days I am free and trying to learn C language as well as Linux. I personally like the way you teach and I am really impressed.

    God bless you

    Regards,

    Hello there my dear Sir, you seem to make linux very easy to use and I’m very thankful you do all these stuff for free. Can you also make a tutorial about compiling kernels and setting up LAMP server?

  • cojo

    Thanks for taking me from zero to where i am now .
    These tutorials are GREAT!

  • Mike

    OK here is my question.
    I have been told to use SUSE Linux ….and have both the KDE desktop version and the Enterprise server version installed on my external disk and can bring them up using VMPlayer.
    I have not started studying them yet.
    Please comment on ” Ubuntu being the choice of technologists”
    I love your videos and think I would learn faster seeing the Linux series….is there a distro for server? or is it a conbined iso image that asks what one wants to install?
    The idea here is to learn the server (not keen on the desktop part) and use it to install applications.
    Any feedback would be appreciated.

    Regards

  • manikanta

    I am a System Administrator and want to learn Storage (Linux Storage)..

    Could you please give me some resources to learn Linux Storage(EMC or Netapp)?

  • Duc

    Hi,
    I am planning to run Linux from an USB-Stick or ext. HDD, and want use it mainly for Wlan, so an OS where I can install a lot of software for this purpose would be a good idea. It would be nice if I could avoid the use of the internal HDD of the netbook for preventing malware etc..
    Someone with a good idea? Thanks a lot.
    Kind regards, Duc

    PS: I do not hold a degree in CS!

  • Joshua
