logger

Add messages to the system log. More information: https://manned.org/logger.

• Log a message to syslog:

logger {{message}}

• Take input from stdin and log to syslog:

echo {{log_entry}} | logger

• Send the output to a remote syslog server running at a given port. Default port is 514:

echo {{log_entry}} | logger {{[-n|--server]}} {{hostname}} {{[-P|--port]}} {{port}}

• Use a specific tag for every line logged. Default is the name of logged in user:

echo {{log_entry}} | logger {{[-t|--tag]}} {{tag}}

• Log messages with a given priority. Default is user.notice. See man logger for all priority options:

echo {{log_entry}} | logger {{[-p|--priority]}} {{user.warning}}
