NAME
     logger -- make entries in the system log

SYNOPSIS
     logger [-46Ais] [-f file] [-h host] [-P port] [-p pri] [-t tag] [message ...]

DESCRIPTION
     The logger utility provides a shell command interface to the syslog(3) system log module.

     The following options are available:

     -4      Force logger to use IPv4 addresses only.

     -6      Force logger to use IPv6 addresses only.

     -A      By default, logger 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, logger tries to send the message to all addresses.

     -i      Log the process id of the logger process with each line.

     -s      Log the message to standard error, as well as the system log.

     -f file
	     Read the contents of the specified file into syslog.

     -h host
	     Send the message to the remote system host instead of logging it locally.

     -P port
	     Send the message to the specified port number on a remote system, which can be specified as a service name or as a decimal number.
	     The default is ``syslog''.  If an unknown service name is used, logger prints a warning and falls back to port 514.

     -p pri  Enter the message with the specified priority.  The priority may be specified numerically or as a ``facility.level'' pair.  For exam-
	     ple, ``-p local3.info'' logs the message(s) as informational level in the local3 facility.  The default is ``user.notice.''

     -t tag  Mark every line in the log with the specified tag rather than the default of current login name.

     message
	     Write the message to log; if not specified, and the -f flag is not provided, standard input is logged.

EXIT STATUS
     The logger utility exits 0 on success, and >0 if an error occurs.

EXAMPLES
	   logger System rebooted

	   logger -p local0.notice -t HOSTIDM -f /dev/idmc
