I have a timetable in a text file that looks like this:

00:05 - 00:54 Dédicace, À léon werth

00:54 - 01:37 Premier chapitre. Lorsque j'avais six ans

01:36 - 02:06 J'ai montré mon chef-d'œuvre

I'm trying to cut an mp3 file into multiple small ones according to this timetable, so the requirements are:

1. I want to do it with bash. I have learned how to do one file. But a timetable is out of my current bash skills.
2. The column with words serve as the names for files.
3. I would like the files to be enumerated like this: 01.Dédicace_À_léon_werth.mp3 02.Premierchapitre_Lorsque_j'avais_six_ans.mp3

And so on.
