Line breaks are displayed correctly, I tested that.

Originally I wanted to avoid to parse complete logs to search for certain strings, as logs can grow very big eventually. So I settled with 'tail' and a fixed number.  But you are right, 15 lines are useless in most cases. I will both add a logrotate entry for the logs and and display the significant part of the logs ( the part tat starts with  "====...") after I finished my current tasks.
