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).

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