. This option cannot
be combined with a command-line message.
h,
−help

n,
−server
server

using UDP instead
of to the builtin syslog routines.
P,
−port
port
Use the specified UDP port
. The default port
number is 514.
p,
−priority
priorityEnter the message into the log with the specified
priority.
The priority may be specified numerically or as a
facility.level
pair.
For example, −p
local3.info
logs the message as informational in
the local3 facility. The default is user.notice
.
s,
−stderr

t,
−tag

.
u,

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.
