 +$ journalctl --disk-usage 
 +Journals take up 3.8G on disk.</​code>​ 
 +  * You can control the size of this directory using this parameter in your ''/​etc/​systemd/​journald.conf'':​ \\ ''​SystemMaxUse=50M''​ 
 +  * You can force a log rotation: <​code>​ 
 +$ sudo systemctl kill --kill-who=main --signal=SIGUSR2 systemd-journald.service </​code>​

 +$ sudo systemctl restart systemd-journald.service </​code>​
