Gestion de liens dynamiques

cre.sh
#/bin/bash
#(ne pas utiliser sh car l'IFS \n ne fonctionne pas!!!! )
#Auteur Bertrand VANDEPORTAELE 2013
#Ce script permet de construire une arborescence dans un dossier vide (définit par $DEST) dans laquelle des liens dynamiques
#vont pointer vers des fichiers/dossiers respectant la même arborescence mais sur plusieurs disques distincts
#Utile pour un média center avec plusieurs disques, on peut ainsi lister dans une même dossier le contenu des différents disque et naviguer comme s'il n'y avait qu'un disque
#exemple: 2 disques durs /media/HD1 et /media/HD2, contenant chacun les dossiers hd et 3D
#on cree sur ~/films/ les dossiers hd et 3D
#puis on crée des liens symboliques de tous les fichiers /media/HD1/hd et /media/HD2/hd vers ~/films/hd
#                               et  de tous les fichiers /media/HD1/sd et /media/HD2/sd vers ~/films/sd
