Si quelqu'un a fait un malencontreux rm des fichiers du répertoire <rep> des process du user <user>, le répertoire <rep> est vide mais les process sont toujours en machine avec les fichiers ouverts.
Avec la commande suivante, on récupère les fichiers :
cd /proc find * -user <user> -links 0 -type f | while read f do x=`echo $f | sed 's!/!_!g' ` echo ln $f <rep>/$x done | sh -x
