 LOGGER(1)               System General Commands Manual               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 sys­
               log 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
 
SEE ALSO
      syslog(3), syslogd(8)
 
 STANDARDS
      The logger command is expected to be IEEE Std 1003.2 (``POSIX.2'') com­
      patible.
