+
+Le journal courant est archivé, un nouveau est crée
+
+```bash
+$ sudo journalctl --rotate
+```
+
+##### Supprimer les journaux vieux de plus de 2 jours:
+
+```bash
+# 2h(ours), 2m(onths), 2w(eeks)
+
+$ sudo journalctl --vacuum-time=2d
+
+Vacuuming done, freed 0B of archived journals from /var/log/journal.
+Deleted archived journal /var/log/journal/5fd6a638ff89491ab71a5b5150cf1c13/user-10001@74abf00168a74a3884bd8c3fc35ea7c1-0000000002757ece-0005fb79b9881a67.journal (8.0M).

+```
+
+##### Garder 5 fichiers de journaux:
+
+```bash
+$ sudo journalctl --vacuum-files=5
+```
+
+##### Nettoyer automatiquement les vieux journaux:
+
+```bash
+# Sauvegarder le fichier de config de journald
+$ cp /etc/systemd/journald.conf /etc/systemd/journald.conf.back
+
+# Editer le fichier de configuration de journald
+$ sudo nano /etc/systemd/journald.conf
+
+# Décommenter la ligne SystemMaxUse
+SystemMaxUse=250M
+
+# Redémarrer journald
+$ sudo systemctl restart systemd-journald
+```
