Synopsis

                  syslogd [options]

System administration command. sysklogd provides both syslogd and klogd functionality. By default, it is meant to behave exactly like the BSD version of syslogd. While the difference should be completely transparent to the user, sysklogd supports an extended syntax. It is invoked as syslogd.

A message can contain a priority code, marked by a number in angle brackets at the beginning of the line. Priorities are defined in <sys/syslog.h>. syslogd reads from an Internet domain socket specified in /etc/services. To bring syslogd down, send it a terminate signal. See also klogd.
