LOGGER(1)                   General Commands Manual                  LOGGER(1)

     logger - make entries in the system log

     logger [-cins] [-d SD] [-f file] [-m msgid] [-p pri] [-t tag]
            [message ...]

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


     -c         Log to console (LOG_CONS).

     -d sd      Log this in the structured data (SD) field.  (sd has to be
                passed as one argument and will require careful quoting when
                used from the shell.)

     -f file    Log the specified file.

     -i         Log the process id of the logger process with each line

     -m msgid   The MSGID used for the message.

     -n         Open log file immediately (LOG_NDELAY).

     -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

     -s         Log the message to standard error, as well as the system log

     -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.

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

           logger System rebooted

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

     syslog(3), syslogd(8)

     The logger utility conforms to IEEE Std 1003.2-1992 ("POSIX.2").
