Only for minicomputer for commercial applications • People were looking for a UNIX based system, which is cheaper and can run on PC • Both DOS, Mac and UNIX were proprietary, i.e., the source code of their kernel is protected • No modification is possible without paying high license fees

  7. Historical Development of Linux • Linus Torvaldsbecame interested in a freeware product called Minix • Developed by Andrew S.Tanenbaum, Minixwas a clone of the commercial UNIX operating system for PCs • In Sept 1991, Torvalds, a second year student of Computer Science at the University of Helsinki, developed the preliminary kernel of Linux, known as Linux version 0.0.1 • And the rest is history …

  8. Linux Distributions • Today, there are hundreds of different distributions available • Popular Linux distributions include: • Ubuntu, SUSE, RedHat/Fedora, Arch, Debian, CentOS, Mint, PCLinuxOS, Mageia • List of distributions: • http://en.wikipedia.org/wiki/List_of_Linux_distributions

  11. Terminal & Command Line • Why use a terminal or command line? • The terminal is a powerful and invaluable tool that can be used to perform many useful tasks you might not be able to accomplish with a GUI • The command-line interface is sometimes a faster way to accomplish a task. • Learning the command-line interface is the first step towards more advanced troubleshooting, system administration, and software development skills • Gives access to a ‘shell’ • One of the most popular is ‘bash’

  12. Basic Commands • Start terminal: • Dash ‣ Applications ‣ Terminal

  13. Ubuntu Setup • Install Cinnamon • Open a ‘terminal’ • Enter the following commands: $ sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable $ sudoapt-get update $ sudoapt-get install cinnamon • Logout
