So today, I was setting up Latex in Ubuntu. And actually, it is installed by default in Ubuntu 9.10, but if you don't have it in your version of Ubuntu, all you have to do is type:
sudo apt-get install texlive

in the shell. sudo apt-get install <package name> is the command you use for installing any package in Ubuntu.

Once you do this, you can compile a simple LaTeX file by typing:

latex test.tex

where test.tex is the file you want to compile.

This will generate two important files:


The test.dvi is the output of file (dvi stands for device indipendent), and test.log is the log file
(it contains information about the compilation process and any warning and error messages). If something goes wrong be sure to check test.log.
To display the content of the file simply type:

less test.log
more test.log

in the shell.

Now, back to test.dvi. There are ways for viewing dvi files in Ubuntu, but, we won't go there. Usually when you use Latex, you want to get ps (post script) file
or pdf (portable document format) file. To get a ps file, you need to type in:

dvips test.dvi

The first command converts the dvi file into a ps file. The second command displays the content of the ps file. For the second command to work, you need to have
gv (ghostviewer) installed. If this is not the case, just type in sudo pat-get install gv. After you have successfully completed the previous steps, all you have to do
to get a pdf version of your file is to type:


This last command will convert the ps file into a pdf file. To view the pdf file type:

evince test.pdf

and the file will open in a Document Viewer.

Well, that's all folks :-D, have fun.
