syslogd
reads and logs messages to the
system console, log files, pipes to other programs, other machines and/or
users as specified by its configuration file.
The options are as follows:
-a
pathsyslogd
should place an
additional log socket. Up to about 20 additional logging sockets can be
specified. The primary use for this is to place additional log sockets in
/dev/log of various chroot filespaces, though the
need for these is less urgent after the introduction of
sendsyslog(2).-d
-f
config_file-h
-m
mark_interval-n
-u
option on a loghost with no
DNS cache. Messages from the local host will still be logged with the
symbolic local host name.-p
log_socket-s
reporting_socketAF_LOCAL
socket for use in
reporting logs stored in memory buffers using
syslogc(8).-u
syslogd
reads its configuration file when
it starts up and whenever it receives a hangup signal. For information on
the format of the configuration file, see
syslog.conf(5).
syslogd
creates the file
/var/run/syslog.pid, and stores its process ID
there. This can be used to kill or reconfigure
syslogd
.
syslogd
opens an Internet domain socket as
specified in /etc/services. Normally
syslogd
will only use this socket to send messages
outwards, but in “insecure” mode it will also read messages
from this socket. syslogd
also opens and reads
messages from the UNIX-domain socket
/dev/log, and from the special device
/dev/klog (to read kernel messages).
syslogd
opens the above described socket
whether or not it is running in secure mode. If
syslogd
is running in secure mode, all incoming data
on this socket is discarded. The socket is required for sending forwarded
messages.
The message sent to syslogd
should consist
of a single line. The message can contain a priority code, which should be a
preceding decimal number in angle braces, for example,
“⟨5⟩”. This priority code should map into the
priorities defined in the include file
<sys/syslog.h>
.

The syslogd
command appeared in
4.3BSD.
syslogd
does not create files, it only
logs to existing ones.
