Introduction – What is Linux



Linux is an operating system
Linux is FREE
Linux is perfect for software development
–

Linux is perfect as a SERVER
–

Web, email, ftp, NFS file, application
Linux is NOT great for 3D gaming
–

Many common IDEs and compilers are FREE
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 you’ve 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. I’d
recommend around 8GB. No less than
3. Enter you CCU userid, but you may
want to use a different password. Then
click Install.
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.
After BIOS Post You’ll See
Again, make sure that after the initial install, you let Windows completely
reboot and then gracefully shutdown before selecting Ubuntu on
subsequent boots.
After Logging Into Ubuntu You’ll See
Networking
The “Panel”
Menus
FireFox
Now we should do some initial configuration
Adding “Widgets” to the Panel


Right-click on the
panel, and click “Add to
Panel”
I personally like:
Frequency Scaling
Battery Monitor
System Monitor
Weather
WorkSpace Switcher
Screen Lock
After Adding Widgets You’ll See
HINT: You can configure many widgets by right-clicking on them.
Check Out What’s In the Menus



Just look around and see the names of what is
there.
We’ll be needing a terminal later, so go to:
Applications Accessories
Then move the mouse over “Terminal” and
LEFT-CLICK and click “Add to Panel”
Now might be a good time to “get on the
network”
Getting On the Network

Click on the network icon
and select CCUUnwired.

If this is not available, your
wireless chipset may not be
‘easily’ supported by
Ubuntu. Try connecting your
laptop to a wired Ethernet
connection.
As you laptop connects, you’ll see
some animation here.
After successfully connecting to
wireless, you should see:
Adding New Free Software


Synaptic is one way of
searching for and
adding new software.
It can be found in:
System
Administration 
Synaptic
You’ll need you password to access this
feature
Installing the Sun Java SDK




In Synaptic, do a search for “Sun Java”
Scroll down and look for “sun-java6-sdk”
Click the box and click “Mark for Installation”
Then click “Apply” in Synaptic, and then “Apply” again
Let’s 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. (you’ll
want to specify where to save files)
Go to: http://ww2.coastal.edu/wjones/linux
Save the hello.tar.gz file to
/home/<your userid>/
Then open a terminal using this icon you
installed on the panel.
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, we’re 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?
Changing Directories (Folders)




Type “cd hello”
This switches you to the “hello” subdirectory
Do another “ls”, what do you see?
There are many linux commands, don’t worry
if you feel a little overwhelmed at first
Compiling a Java program


Type “javac hello.java”, press enter
Do an “ls” what has now appeared in the
directory?

To run the java program, type “java hello”,
press enter.

Check out the java code on the next slide:
What Does This Code Do?
Try Passing a Command-line Parameter

Type “java hello John”
Type “java hello 10”

What seems to be the case?

Now For Some More Fun




Go to the synaptic package manager
Search for “chromium”
Install it
Run it by going to
“ApplicationsGamesChromium”
OpenOffice
A Free Alternative to MSOffice

From Ubuntu Menu at top left of screen: Goto:
Applications Office  OpenOffice Word Processor

After it opens, type out a short test memo and save it as a MS Word
97/2000/XP file (using the File menu)

In Firefox, login to your CCU webmail and email yourself a copy of
the file. Later in Windows, see if you can open the file. Does it look
the same?

In OpenOffice, try exporting the file as a PDF (in the File Menu)

From Ubuntu Menu at top: Goto: Places  Documents Find the
exported PDF of the test memo. Double Click on it.
PDFs Continued

What application opened the PDF document?
–
Hint, after it opens, goto Help About in that application

What if I want to use Acrobat Reader?

It doesn’t seem to be in the Synaptic Package Manager.
(search for adobe or acrobat). That’s because Acrobat
Reader in not in one of the repositories that come loaded
in Ubuntu due to legal reasons. To add this repository,
goto:
https://help.ubuntu.com/community/Medibuntu

Adding New Repository From the
Command Line




Folllowing the directions on that site:
Open a terminal and type:
sudo wget
http://www.medibuntu.org/sources.list.d/hardy.list -O
/etc/apt/sources.list.d/medibuntu.list
Then type:
sudo apt-get update && sudo apt-get install medibuntukeyring && sudo apt-get update
(These lines can be copied/pasted by highlighting the
string in the browser, and then using the middle mouse
button in the terminal)
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.
Then search for adobe and select ‘acroread’. Apply
this, and install it.
In a new terminal (or in the one that was already
open type rehash), type acroread
This should open acrobat reader.
Reopen PDF in Acroread







Double-click on the test memo in Places 
Documents
Does it open in acroread?
So, right-click on the document icon, and select with
“open with application”
If acrobat is not listed there, we need to browse to it
on the HDD. Where would it be?
Open a terminal and type: which acroread
That will tell you the path
Navigate to this location under the browser, and now
it will open with acroread.
Gimp
GNU Image Manipulation Program

Goto FileNewImage
Accept default options
Draw in the image.
Goto: File  Save As
Look at all the types of files Gimp to export to.
Much more than MS Paint!

connect to it from Ubuntu.
Killing a Process






Got an application ‘hung’ or the CPU is always
at 100%, you may need to kill a process.
Can be done from command-line, but:

Locate the firefox process in the System
Monitor.
Kill it
