logger

Add messages to syslog (/var/log/syslog).

• 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 --server {{hostname}} --port {{port}}

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

echo {{log_entry}} | logger --tag {{tag}}

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

echo {{log_entry}} | logger --priority {{user.warning}}
