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 (LOG_PERROR). -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.
