Use journalctl to View Your System's Logs

View journalctl without Paging

To send your logs to standard output and avoid paging them, use 

        the --no-pager option:

journalctl --no-pager

It's not recommended that you do this without first filtering down 

        the number of logs shown.

journalctl -u service-name.service︙

Show Logs within a Time Range

Use the --since option to show logs after a specified date and 

            time:

journalctl --since "2018-08-30 14:10:10"

Use the --until option to show logs up to a specified date and time:

journalctl --until "2018-09-02 12:05:50"

Combine these to show logs between the two times:

journalctl --since "2018-08-30 14:10:10" --until "2018-09-02 12:05:50"
