Running Sage from the commad line in Ubuntu 12.04

I'm relatively new to Sage and to GNU/ Linux. Sorry in advance if this question seem silly. But I need to learn how to do this. Here is my problem:

I have Sage installed from source in /usr/local/src. So every time I want to run Sage I have to type on the terminal

$ cd /usr/local/src/sage-5.4.1/

and once inside this directory, I have to type

./sage

How can I start Sage directly at the prompt $ just by typing "sage"?

Thanks a lot for the answer.

Open $HOME/.bashrc in a text editor and add the path to the PATH environment variable by adding this line to the file

export PATH="/usr/local/src/sage-5.4.1:$PATH"

Save the file and either open a new terminal, or type exec bash in the current terminal. Just sage should work now. You will need to edit the above line whenever you have a new Sage installation. This is a standard unix way of making things work without giving the absolute path to the commands. Search Google for unix PATH to learn more.
