Introduction What is Linux

• Linux is an operating system
• Linux is FREE
• Linux is perfect for software development
• Many common IDEs and compilers are FREE
• Linux is perfect as a SERVER
• Web, email, ftp, NFS file, application
• Linux is NOT great for 3D gaming
• Not many titles are released for Linux
• There are many distributions of Linux
• Ubuntu, RedHat, Fedora, Debian, Suse, Gentoo,
  Slackware, etc

Installing Ubuntu

• There are many ways to install Ubuntu. Some
  (common ways) require resizing and
  re-partitioning your hard drive. Since youve
  probably already got Windows XP or Vista running
  on your laptop, a fast and safe(er) way to
  install it is by installing it from the CD as the
  directions that follow prescribe.
• First, boot into Windows and place the CD in the
  drive. If it does not autorun, go to the drive in
  My Computer for example, and double click on it.

After Booting into Windows
1. Click on Install Inside Windows
2. You have to choose a potential size of the
file system you want to have access to after
Ubuntu is installed. Id recommend around 8GB. No
less than 3. Enter you CCU userid, but you may
want to use a different password. Then click
Install.
This will take some time, be patient, its worth
it!
5
After Initial Installation
Click Finish to Reboot Now. It is VERY important
that you allow your computer to completely reboot
into Windows first before trying to enter Ubuntu.
Gracefully shutdown Windows, and then after BIOS
post, select Ubuntu from the bootloader.
6
After BIOS Post Youll See
Again, make sure that after the initial install,
you let Windows completely reboot and then
gracefully shutdown before selecting Ubuntu on
subsequent boots.

11
Getting On the Network

• Click on the network icon and select CCUUnwired.

  may not be easily supported by Ubuntu. Try
  connecting your laptop to a wired Ethernet
  connection.

Adding New Free Software

  new software.

• Scroll down and look for sun-java6-sdk
• Click the box and click Mark for Installation

Lets Download a Linux-type Zip File

• Linux often uses a tar.gz file type to
  agglomerate and compress multiple files
• You may need to set the preferences in Firefox to
  ask you for a save locations. (youll want to
  specify where to save files)
• Go to http//ww2.coastal.edu/wjones/linux
• Save the hello.tar.gz file to /home/ltyour
  useridgt/
• Then open a terminal using this icon you
  installed on the panel.

15
Unzipping the file

• Once the terminal appears, you should be able to
  type ls at the command prompt and see your
  files.
• Keep in mind, Linux has all the same abilities to
  use things like explorer and other GUI
  interfaces in Windows using point and click, but
  for the sake of learning something new, were
  doing it this way.
• You should see the file hello.tar.gz
• At the prompt, type tar xvfz hello.tar.gz
• You can use the tab key to quickly spell out the
  rest of the name for you, type typing just the
  first couple letters of the filename and then
  press tab.
• Now, press enter.
• Now type ls again, what do you see now?

16
Changing Directories (Folders)

• Type cd hello

  feel a little overwhelmed at first

  save it as a MS Word 97/2000/XP file (using the
  File menu)

  yourself a copy of the file. Later in Windows,
  see if you can open the file. Does it look the

  the string in the browser, and then using the
  middle mouse button in the terminal)

24
Finish Installing Acrobat Reader

• After that is done, reopen Synaptic, and do a
  reload. You may get a message about Medibuntu not
  being authenticated. Accept it.
