# systemd-cat
|
|
|
|
> Connect a pipeline or program's output streams with the systemd journal.
|
|
> More information: <https://www.freedesktop.org/software/systemd/man/latest/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}}`
|
