LOGGER(1)

NAME

     logger -- make entries in the system log

SYNOPSIS

     logger [-46Ais] [-f file] [-h host] [-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
	     Log the specified file.

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

     -p 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 informational
	     level in the local3 facility.  The default is ``user.notice.''

     -t tag  Mark every line in the log with the specified tag.

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

DIAGNOSTICS

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

EXAMPLES
