A systemd component called journald collects and manages journal entries from all parts of the system. This is basically log information from applications and the kernel.

1. To see all log entries, starting at the oldest entry

journalctl

2. journal entries from the current boot

journalctl -b

3. To see only kernel messages, such as those that are typically represented by dmesg

journalctl -k

To see the above only from the current boot

journalctl -k -b
