LOGGER(1)               NetBSD General Commands Manual               LOGGER(1)


NAME

     logger -- make entries in the system log


SYNOPSIS

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


DESCRIPTION

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

     Options:

     -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.

     -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''.

     -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.


EXIT STATUS

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


EXAMPLES
