You all are really impressive !

Thanks very much for your answers I found the answer to my question and much more !

@AlphaLexman : concerning the use of "ls" in a "for" statement inside a shell (bash in my case) script, I resolved the spaces issue by setting the IFS variable to
IFS="
"
every beginning of my scripts. I didn't mention it in my first post ... I don't know why !

Today this seems not necessary anymore thanks to cfajohnson who learned me correct way to list files within a script.
So simple but really efficient !

Coming back to my initial question, I'll go on with Shell_Life's sed expression which works like a charm.

Anyway I'll keep all the other suggestions in my bag, they are all interesting.

Bye
