In older Linux systems, the
logger command can be used to send a log message to syslog.
Reading where does
logger log its messages to in Arch Linux?, it seems that
syslog messages and the
logger command line app only talk to the
systemd journal if a socket for message forwarding is set up.
So what's the modern equivalent of the
logger command? How can I send a message directly to the systemd journal from the command line?
