NAME

     logger -- a shell command interface to the syslog(3) system log module

SYNOPSIS

     logger [-dhisV] [-f file] [-n server] [-P port] [-p pri] [-t tag] [-u socket] [message]

DESCRIPTION

     logger makes entries in the system log.  It provides a shell command interface to the syslog(3) system log module.

     Options:

     -d, --udp
	      Use datagram (UDP) instead of the default stream connection (TCP).

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

     -f, --file file
	      Log the contents of the specified file.  This option cannot be combined with a command-line message.

     -h, --help
	      Display a help text and exit.

     -n, --server server
	      Write to the specified remote syslog server using UDP instead of to the builtin syslog routines.

     -P, --port port
	      Use the specified UDP port.  The default port number is 514.

     -p, --priority priority
	      Enter the message into the log with the specified priority.  The priority may be specified numerically or as a facility.level pair.
	      For example, -p local3.info logs the message as informational in the local3 facility.  The default is user.notice.

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

     -t, --tag tag
	      Mark every line to be logged with the specified tag.

     -u, --socket socket
	      Write to the specified socket instead of to the builtin syslog routines.

     -V, --version
	      Display version information and exit.

     --       End the argument list. This is to allow the message to start with a hyphen (-).

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

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

     Valid facility names are: auth, authpriv (for security information of a sensitive nature), cron, daemon, ftp, kern (can't be generated from
     user process), lpr, mail, news, security (deprecated synonym for auth), syslog, user, uucp, and local0 to local7, inclusive.

     Valid level names are: alert, crit, debug, emerg, err, error (deprecated synonym for err), info, notice, panic (deprecated synonym for
     emerg), warning, warn (deprecated synonym for warning).  For the priority order and intended purposes of these levels, see syslog(3).

EXAMPLES

	   logger System rebooted

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

	   logger -n loghost.example.com System rebooted

SEE ALSO

     syslog(3), syslogd(8)

STANDARDS

     The logger command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.

AVAILABILITY

     The logger command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.

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
