Code	Name	Content
1	SIGHUP	On behalf of "let the PID reread its own profile", similar to restarting
2	SIGINT	Represents the [Ctrl]-c] entered by the keyboard to interrupt a program.
9	SIGKILL	The representative forces the interruption of a program, and if the program is halfway through, then the unfinished part may have a "half product", similar to what Vim would have. Filename.swp.
15	SIGTERM	Terminate the program with the normal end procedure. Because it is normal to terminate, the subsequent action will be done by him. However, if the program already has a problem, it is not possible to use the normal method of termination, the input of this signal is also useless.

Example 1: After using PS to find the PID of this service, then use Kill to re-read the syslog configuration file data:

kill -sighup 'PS aux| grep ' syslog '| grep ' grep '| awk ' {print $} "'
