Yes! It is possible to only show a limited amount of logs from journalctl. This can be especially helpful if you are maintaining a heavily-used machine and you only want to know the last few sudo-related logs. You can run the following command in your terminal:
sudo journalctl --lines=10 -e /usr/bin/sudo
Doing this will tell journalctl that you only want it to display the last 10 sudo-related entries that it logged while it is running.
It is also possible to only display time-specific logs from journalctl. This command will tell journalctl to only print all the sudo-related logs that were committed between yesterday and today:
sudo journalctl --since=yesterday --until=today -e /usr/bin/sudo
