journalctl is the systemd tool for viewing and tailing system logs. It's cool but has one infuriating bug: when you hit ^C,
it kills both journalctl and your pager.
less has lots of useful behavior based on
^C (such as to stop tailing a log), so this makes
useless in my view :)
It sets the
K option on
less which has this effect, but then it also sends SIGTERM itself when
SIGINT, so unsetting that
K is not effective, either.
