Metal enrichment, clustering properties and main heating process of the intergalactic medium can be probed by analyzing the numerous Lyman 'forest' lines in the spectra of distant quasars and their associated, absorption metal lines. Constraints can then be placed on the scenarii of structure formation, the origin of metals and how they have been expelled in the intergalactic medium, and the spectral shape of the metagalactic UV flux.
