Linux[1] (bsdutils package) and most BSDs including MacOS provide logger command line utility to send messages to syslog, locally or to a remote syslog server. Many languages provide support for writing messages to syslog, such as go: https://godoc.org/github.com/spkg/slog.
Basic Usage[edit]
logger -s "Message"
-s, --stderrOutput the message to standard error as well as to the system log.
logger --server 10.10.x.x "TEST"
echo "MY TEXT TO LOG" | logger -s
-s, --stderrOutput the message to standard error as well as to the system log.
logger -n SERVER.DOMAIN.COM -T "TEST
logger: failed to resolve name SERVER.DOMAIN.COM port syslog-conn: Servname not supported for ai_socktype
logger -n SERVER.DOMAIN.COM -T -P 514 "TEST
