Actually the 'tput' command mentioned in this article solved the problem for me :)
I guess for my humble shell script it's the best solution...
Thanks for all the info Guys.

Hi List. I have a script that produce output to the standard terminal (a shell window in Linux). For example:
[snip]
But... I want to understand exactly what happens and also to find out if this is the best and most elegant solution. I would appreciate a nice solution but also a direction to some written man that describe it. BAsically, I want to understand how this is done in the technical level (I mean who is responsible the OS or the Shell) so that my code could be run on different distributions of the same OS or different shells.
Well, the shell is responsible for output formatting, including colours.
The bash way of colouring output (including colour codes) is described in: http://archives.real-time.com/pipermail/tclug-list/2002-March/048795.html
The colors are produced by the terminal emulation. In the case of a virtual console, that is done by, I think, the kernel. In the case of X, that is done by whatever program you opened (xterm, konsole, etc.).
The commands you describe above are the ANSI, or VT100, command set. These were used by the traditional VT100 digital terminal, and are now used by VT100 terminal emulators. There are, however, many other standards.
If you want your escape sequences to work on 90% of the cases, just use the codes above. If you want them to work on 100% of the cases, RTFM ncurses.
