.Sh NAME
.Nm logger
.Nd make entries in the system log
.Sh SYNOPSIS
.Nm
.Op Fl 46Ais
.Op Fl f Ar file
.Op Fl h Ar host
.Op Fl P Ar port
.Op Fl p Ar pri
.Op Fl t Ar tag
.Op Ar message ...
.Sh DESCRIPTION
The
.Nm
utility provides a shell command interface to the
.Xr syslog 3
system log module.
.Pp
The following options are available:
.Bl -tag -width indent
.It Fl 4
Force
.Nm
to use IPv4 addresses only.
.It Fl 6
Force
.Nm
to use IPv6 addresses only.
.It Fl A
By default,
.Nm
tries to send the message to only one address,
even if the host has more than one A or AAAA record.
If this option is specified,
.Nm
tries to send the message to all addresses.
.It Fl i
Log the process id of the logger process
with each line.
.It Fl s
Log the message to standard error, as well as the system log.
.It Fl f Ar file
Log the specified file.
.It Fl h Ar host
Send the message to the remote system
.Ar host
instead of logging it locally.
.It Fl P Ar port
Send the message to the specified
.Ar port
number on a remote system,
which can be specified as a service name
or as a decimal number.
The default is
.Dq Li syslog .
If an unknown service name is used,
.Nm
prints a warning and falls back to port 514.
.It Fl p Ar pri
Enter the message with the specified priority.
The priority may be specified numerically or as a ``facility.level''
pair.
For example, ``\-p local3.info'' logs the message(s) as
.Ar info Ns rmational
level in the
.Ar local3
facility.
The default is ``user.notice.''
.It Fl t Ar tag
Mark every line in the log with the specified
.Ar tag
rather than the default of current login name.
.It Ar message
Write the message to log; if not specified, and the
.Fl f
flag is not
provided, standard input is logged.
