Use journalctl (systemd) with less, cat or tail

journalctl-and-less.txt

By default, `journalctl` will print the logs through a pager which can hide results from you. This can be annoying when trying to capture a screenshot:

root@docker01:~# journalctl -xe -u docker
May 21 23:25:40 docker01 dockerd[123]: time="2020-05-21T23:25:40.376573968Z" level=info msg="ign
May 22 00:45:37 docker01 dockerd[123]: time="2020-05-22T00:45:37.971043364Z" level=info msg="ign
lines 1006-1046/1046 (END)

Instead, pipe `journalctl` through `less`, `cat` or `tail` to quickly get familiar features such as wrapped lines:

root@docker01:~# journalctl -xe -u docker
...
May 21 23:25:40 docker01 dockerd[123]: time="2020-05-21T23:25:40.376573968Z" level=info msg="ignoring event" module=libcontainerd namespace=moby topic=/tasks/delete type="*events.TaskDelete"
May 22 00:45:37 docker01 dockerd[123]: time="2020-05-22T00:45:37.971043364Z" level=info msg="ignoring event" module=libcontainerd namespace=moby topic=/tasks/delete type="*events.TaskDelete"
(END)
