Your post has been split away to stand on its own.
The original thread was an instructional posting.
Your question hijacks it away for some query on something you are experiencing.
ALWAYS start a new post when you have a question.
NEVER hijack someone else's thread away.
That is how you use proper forum etiquette.
Since your question is a "How do I install" post, it has been moved to the appropriate forum space.
Actually it should not matter and you can cut and paste the commands shown in the Terminal window line by line or at once as shown. However, the recently upgraded OTN forum software apparently started to mess up copy and paste and adds an additional empty line after each line when pasting the text as a whole, which results in an error.
You may have to copy and paste the text line by line and make sure not to copy the line ending.
For what it's worth: Copy of text results in double line spacing.
There are two ways how you can copy a complete line of text:
a) move the mouse to the beginning of the line, click, hold and move the cursor to the end of the line.
b) move the mouse to the beginning of the line, click, hold and move the cursor to the next line.
Due to some issue, unfortunately you will have to use option a.
I did follow the steps on the forum but didn't work for me but, I have a few question I would like to ask you.
first, I am new to Linux and I don't know how programs suppose to work or run here.
I unzip the folder with a tool from Ubuntu 12.04 "Archive Manager" I make my sqldeveloper.sh file and then I go to the terminal and run it. Then sql asks me for a path to the jdk and says that the path will be save into a .sqldeveloper directory in home directory, I give /usr/lib/jvm/java-6-openjdk-i3876, then the program launches and still open as long as I don't close it or close the terminal. Question: is that a successful installation? if that is correct what I need to do is somehow create a way to launch the program without going to the terminal and run the file each time I want to work into Oracle SQL, can you help me out please with directions? I am running Ubunto 12.04
output from terminal while I am running sql:
dataminer jdbc jviews sleepycat sqldeveloper.sh
icon.png jdev modules sqldeveloper sqlj
ide jdev.label rdbms sqldeveloper.desktop timingframework
javavm jlib readme.html sqldeveloper.exe view-source-paths.lis
Oracle SQL Developer

Type the full pathname of a J2SE installation (or Ctrl-C to quit), the path will be stored in ~/.sqldeveloper/jdk
Perhaps you did not notice, but if you install Ubuntu 32-bit, which should be rather be obsolete these days, the path to your Java development kit installation is not /usr/lib/jvm/java-6-openjdk, but /usr/lib/jvm/java-6-openjdk-i386 instead.
So in step 3 of the instructions, simply replace jvm/java-6-openjdk with jvm/java-6-openjdk-i386
Regarding your IO error with the network adapter, please provide more details how to reproduce the problem. You will probably want to post this in the Generic Linux forum though, since the problem is most likely not SQL Developer related.
