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

• Use the specified identifier (default: cat when reading from a pipeline, executable name otherwise):

{{command}} | systemd-cat {{[-t|--identifier]}} {{id}}

• Use the specified default priority level for all logged messages:

systemd-cat {{[-p|--priority]}} {{emerg|alert|crit|err|warning|notice|info|debug}} {{command}}

• Use the specified default priority level for the logged messages from the command’s stderr:

systemd-cat --stderr-priority {{emerg|alert|crit|err|warning|notice|info|debug}} {{command}}
