pri

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 (

-
- -t
tag
- Mark every line in the log with the specified
tag.
-
