syslog(3) system log module.
Options:
-
-c

Open log file immediately (LOG_NDELAY).
-
-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 (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.
