logger [-isd] [-f file] [-p pri] [-t tag] [-u socket] [message ...]
DESCRIPTION
Logger provides a shell command interface to the syslog(3) system log
module.
Options:
-i Log the process id of the logger process with each line.
-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
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.''
-t tag Mark every line in the log with the specified tag.
-u sock Write to socket as specified with socket instead of builtin sys
log routines.
-d Use a datagram instead of a stream connection to this socket.
-- End the argument list. This is to allow the message to start
with a hyphen (-).
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.
Valid facility names are: auth, authpriv (for security information of a
sensitive nature), cron, daemon, ftp, kern, lpr, mail, news, security
(deprecated synonym for auth), syslog, user, uucp, and local0 to local7,
inclusive.
Valid level names are: alert, crit, debug, emerg, err, error (deprecated
synonym for err), info, notice, panic (deprecated synonym for emerg),
warning, warn (deprecated synonym for warning).
