The following programs/files/directories will be discussed for this topic:

  • exit
  • What group was involved in creating UNIX? What did they first try to make?
  • Who were the people involved in making UNIX? For Linux? What were their reasons?
  • Why did UNIX (and later Linux) become so widespread? What language was it converted to, so as to make it more portable?
  • Who invented that language, and where did he work?
  • Why do we use ssh and not telnet?
  • How do you properly disconnect from our Linux machine?
  • What is meant by the "flavors of UNIX/Linux"? And what flavor are we using right now?
  • When was Linux Created? By who?
  • How is a "server" machine different from a "desktop or workstation" machine? Can a machine be both?
  • What are the four parts of an OS? What do some "purists" argue is the onlye ONE part of an OS?
Activities & Assignments
  • Go to my internet page and check out the "Web page resources" section, and find both the "Cheat Sheet for Lampbusters Students" and the link to download Putty.
  • Use the cheat sheet to log into lampbusters.com using putty. You can create a web page if you want, but it's not required.
  • Try the ^c and ^l commands, see if you can figure them out.
  • Please read How to Survive this Course
  • As always, the book's index, or one of the many resources on the How to find answers page.
  • And of course, the main website for your os (CentOS) and search engines such as Google one of my favorites.
