Hint: Remember that journal tracks each log relative to each system boot. Also, keep in mind that you can sort messages by priority, relative boot, and specific units.

  1. Write the journalctl command that performs a log search that returns all messages, with priorities from emergency to error, since the current system boot.
  2. Write the journalctl command that checks the disk usage of the system journal unit since the most recent boot. You will likely have to pipe this output to less if it doesn’t fit on the screen.
    • The unit you want is systemd-journald.
  3. Write the journalctl command that removes all archived journal files except the most recent two.
  4. Write the journalctl command that filters all log messages with priority levels between zero and two, and save the results to a file named Priority_High.txt in /home/student/ directory.
  5. Automate the last task by creating a cron job that runs daily in the user crontab.

Note: You’ll need sudo to run journalctl.
