logger [-dhisV] [-f file] [-n server] [-P port] [-p pri] [-t tag]
            [-u socket] [message]

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


     -d, --udp
              Use datagram (UDP) instead of the default stream connection

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

     -f, --file file
              Log the contents of the specified file.  This option cannot be
              combined with a command-line message.

     -h, --help
              Display a help text and exit.

     -n, --server server
              Write to the specified remote syslog server using UDP instead of
              to the builtin syslog routines.

     -P, --port port
              Use the specified UDP port.  The default port number is 514.

     -p, --priority priority
              Enter the message into the log with the specified priority.  The
              priority may be specified numerically or as a facility.level
              pair.  For example, -p local3.info logs the message as informa-
              tional in the local3 facility.  The default is user.notice.

     -s, --stderr
              Output the message to standard error as well as to the system

     -t, --tag tag
              Mark every line to be logged with the specified tag.

     -u, --socket socket
              Write to the specified socket instead of to the builtin syslog

     -V, --version
              Display version information and exit.

     --       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
     and intended purposes of these levels, see syslog(3).
