===== Undelete Solaris =====

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 :

<code>
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
</code>
