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

     -f file  Log the specified file.

     -p pri   Enter the message with the specified priority.  The priority may

     -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.
