46.Sh DESCRIPTION
47The
48.Nm
49utility provides a shell command interface to the
50.Xr syslog 3
51system log module.

53The following options are available:
54.Bl -tag -width indent

56Force
57.Nm
58to use IPv4 addresses only.
59.It Fl 6
60Force
61.Nm
62to use IPv6 addresses only.
63.It Fl A
64By default,
65.Nm
66tries to send the message to only one address,
67even if the host has more than one A or AAAA record.
68If this option is specified,
69.Nm
70tries to send the message to all addresses.
71.It Fl i
72Log the process id of the logger process
73with each line.
74.It Fl s
75Log the message to standard error, as well as the system log.
76.It Fl f Ar file
77Log the specified file.
78.It Fl h Ar host
79Send the message to the remote system
80.Ar host
81instead of logging it locally.
82.It Fl P Ar port
83Send the message to the specified
84.Ar port
85number on a remote system,
86which can be specified as a service name
87or as a decimal number.
88The default is
89.Dq Li syslog .
90If an unknown service name is used,
91.Nm
92prints a warning and falls back to port 514.
93.It Fl p Ar pri
94Enter the message with the specified priority.
95The priority may be specified numerically or as a ``facility.level''
96pair.
97For example, ``\-p local3.info'' logs the message(s) as
98.Ar info Ns rmational
99level in the
100.Ar local3
101facility.
102The default is ``user.notice.''
103.It Fl t Ar tag
104Mark every line in the log with the specified
105.Ar tag .
106.It Ar message
