How To Clear The systemd journal Logs

systemd has its own logging system which provides centralized management for logging kernel and userland processes. This article explains how to clear the systemd journal log files.

systemd-journald is a system service that collects and stores logging data. This log data is stored either in /run/log/journal/MACHINE-ID/ (volatile - the journal log data is stored in memory and is lost on reboot) or in /var/log/journal/MACHINE-ID (persistent - the journal data log is stored on disk). On systems which are configured to store the systemd journal data on disk, the logs can take a considerable amount of disk space after some time.
