     - `all` $\rightarrow$ permet de spécifier sur quelles machines de
     l'inventaire le module sera appliqué, en l'occurrence on l'appliquera sur
     toutes les machines de l'inventaire donc H1, H2, R1, R2
+- Donner la commande _ad-hoc_ qui permet d’afficher l’uptime de toutes les
+machines, sans écrire de fichier inventaire. Démontrez que cette commande est
+correcte en l’exécutant sur la topologie

+- Quelle est la différente entre les modules `command`, `shell` et `raw` ?
+Expliquez et donner des exemples.
+    - `command` $\rightarrow$
+    - `shell` $\rightarrow$
+    - `raw` $\rightarrow$ ce module est différent des deux autres dans la mesure
+    où il ne transfère pas de code `python` sur l'hôte distant. La commande
+    spécifié sera exécuté par le daemon `sshd` en créant un processus enfant
+    sur la machine distante
