Provides a command interface to send messages to the syslog daemon who will decide where they should be forwarded to.

example^†:

1. Run myUpdater.sh
2. Send a syslog notice that it ran containing the last line of the stdout
3. Send the log file to the syslog with a priority of info
4. If there return code indicated a problem,
   send the stderr to syslog with priority of error

5. 
   myUpdater.sh 1> /tmp/myUpdater.log 2> /tmp/myupdater.err
   rc=$?
    tail -n1 /tmp/myUpdater.log | logger -p local3.notice 
    logger -p local3.info -f /tmp/myUpdater.log
   if [ $rc != 0 ]; then  
    logger -p local3.err  -f /tmp/myUpdater.err -s 
   fi 

   -i	process id of the logger process
   -s	Log the message to standard error, as well as the system log.
   -f file	Enter the contents of file into the log.
   -p pri	Enter the message with the specified priority.
   -p facility.level	The priority may be specified numerically or as a facility.level pair. -p local3.info level in the local3 facility. The default is user.notice.
   -t tag	tag line .
   -u socket	Write to socket instead of builtin syslog routines. (port 514)
   -d	Use a datagram instead of a stream connection to this socket.
   --	End of options, (allows message to start with a hyphen (-)).
   	if no message is specified standard input is logged

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