This function is intended to generate human-readable output. If you
are looking for computer-parsable output, use show instead. By
default this function only shows 10 lines of output and ellipsizes
lines to fit in the terminal window. This can be changes with
--lines and --full, see above. In addition, journalctl --unit=NAME
or journalctl --user-unit=NAME use a similar filter for messages
and might be more convenient.
