I believe this will imply to dump the original content, add the new and 
rewrite it all. If so, I don't like it, otherwise please explain what you're 
thinking about.

Who said that? Do you think I'm not able to iterate other a set of values? Did 
you understand that from my e-mail address?

That's what I was thinking. Imagine I've got a cd in the driver, and I don't 
know how many sessions are there in the cd, but I know that the cd contains, 
in one of the session, a file I want to read. What I was asking here is if 
there is a way to know how many session are present, thus to easily iterate 
without making my program to try mounting the cd and stopping at the first 
fail, to reach the file I'm looking for. I'd like to do this in bash.

If you don't know the answer, please don't post.
