systemd-cat

Connect a pipeline or program's output streams with the systemd journal. More information: https://www.freedesktop.org/software/systemd/man/systemd-cat.html.

• Write the output of the specified command to the journal (both output streams are captured):

systemd-cat {{command}}

• Write the output of a pipeline to the journal (stderr stays connected to the terminal):

{{command}} | systemd-cat
