what does the S and K in file name under /etc/init.d/rcx.d stand for

Question

I'm using Suse11. I know the /etc/init.d/rcx.d is used for different run levels. And if you list of the directory, let's say rc5.d/. You can see that the filename either start with S or K, so what is the meaning behind this naming convention?

Answer 1

Start or Kill to indicate whether that service should or should not run in that runlevel.
