LOGGER(1)

NAME
logger - make entries in the system log

SYNOPSIS
logger [-isd] [-f file] [-p pri] [-t tag] [-u socket] [message ...]

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

Options:

-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.

-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.

-u sock
    Write to socket as specified with socket instead of builtin syslog routines.

-d  Use a datagram instead of a stream connection to this socket.

--  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, 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
