- is the default and generates an output
- that is mostly identical to the
- formatting of classic syslog
- files, showing one line per journal
- entry. <literal>short-monotonic</literal>
- is very similar but shows monotonic
- timestamps instead of wallclock
- timestamps. <literal>verbose</literal>
- shows the full structured entry items
- with all
- fields. <literal>export</literal>
- serializes the journal into a binary
- (but mostly text-based) stream
- suitable for backups and network
- transfer (see <ulink
- url="http://www.freedesktop.org/wiki/Software/systemd/export">Journal
- Export Format</ulink> for more
- information). <literal>json</literal>
- formats entries as JSON data
- structures, one per
- line (see <ulink
- url="http://www.freedesktop.org/wiki/Software/systemd/json">Journal
- JSON Format</ulink> for more
- information). <literal>json-pretty</literal>
- also formats entries as JSON data
- structures, but formats them in
- multiple lines in order to make them
- more readable for
- humans. <literal>json-sse</literal>
- also formats entries as JSON data
- structures, but wraps them in a format
- suitable for <ulink
- url="https://developer.mozilla.org/en-US/docs/Server-sent_events/Using_server-sent_events">Server-Sent
- Events</ulink>. <literal>cat</literal>
- generates a very terse output only
