.Dd March 21, 2015 .Dt LOGGER 1 .Os .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.
p The following options are available: l -tag -width indent t Fl 4 Force .Nm to use IPv4 addresses only. t Fl 6 Force .Nm to use IPv6 addresses only. t 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. t Fl i Log the process id of the logger process with each line. t Fl s Log the message to standard error, as well as the system log. t Fl f Ar file Read the contents of the specified file into syslog. This option is ignored when a message is also specified. t Fl h Ar host Send the message to the remote system .Ar host instead of logging it locally. t 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. t 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.'' t Fl t Ar tag Mark every line in the log with the specified .Ar tag rather than the default of current login name. t Ar message Write the message to log; if not specified, and the .Fl f flag is not provided, standard input is logged. .El .Sh EXIT STATUS .Ex -std .Sh EXAMPLES d -literal -offset indent -compact logger System rebooted logger -p local0.notice -t HOSTIDM -f /dev/idmc .Ed .Sh SEE ALSO .Xr syslog 3 , .Xr syslogd 8 .Sh STANDARDS The .Nm command is expected to be .St -p1003.2 compatible.
