LOGGER(1)                  OpenBSD Reference Manual                  LOGGER(1)

NAME
     logger - make entries in the system log

SYNOPSIS
     logger [-is] [-f file] [-p pri] [-t tag] [message ...]

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

     The options are as follows:

     -f file  Log the specified file.

     -i       Log the process ID of the logger process with each line.

     -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.

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

EXAMPLES
           $ logger System rebooted

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

SEE ALSO
     syslog(3), syslogd(8)

STANDARDS
     The logger utility is compliant with the IEEE Std 1003.1-2008 (``POSIX'')
     specification.

     The flags [-ifpst] are extensions to that specification.
