La commande strings peut être utilisé pour visualiser le contenu d'un fichier binaire.
Par exemple, pour voir le contenu d'un fichier olr dans un environnement grid infrastructure 11g (en cluster ou en standalone):
sudo su -
cd $GRID_HOME/cdata
strings host1.olr
Exemple de contenu obtenu:
[root@host1 cdata]# strings host1.olr |grep SPFile
