I want to watch output from a systemd service on CentOS as if I have started this service from console. Yes, I can see output with journalctl, but it doesn't scroll to the bottom automatically. So how can I watch live output from service?






systemd journalctl

          journalctl -f -u mystuff.service


          It's in the manual:




          -f, --follow

          Show only the most recent journal entries, and continuously print new entries as they are appended to the
          journal.




          and




          -u, --unit=UNIT|PATTERN

          Show messages for the specified systemd unit UNIT (such as a service unit), or for any of the units
          matched by PATTERN. If a pattern is specified, a list of unit names found in the journal is compared with
          the specified pattern and all that match are used. For each unit name, a match is added for messages from
          the unit ("_SYSTEMD_UNIT=UNIT"), along with additional matches for messages from systemd and messages
          about coredumps for the specified unit.



          This parameter can be specified multiple times.

                    One-line joke

                    A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
