Kill command "-1" This parameter is the killing process or reload?

Kill
-1: A configuration file that reads the parameters again (similar to reload)

This sentence gives me the feeling is to kill the process after the restart process, that is, reload. And I checked the man kill,-1 the corresponding signal is SIGHUP, with a
Find/-perm +7000 >/dev/null 2>&1 &
The order test is actually the killing process, bird brother said the reverse?

• SIGHUP -hangup or exit a foreground running process from a terminal

Reason:
The daemon is a re-read configuration, which kills the normal process.

HUP signal can be intercepted, you can do anything after interception
The general daemon will reload the configuration when this signal is received.
This is a habit, because SIGHUP original meaning to the trustworthiness process has no meaning (SIGHUP is when the control terminal loses the connection to trigger the signal, and the daemon does not control the terminal, so it does not use).
