Autostart scripts in freeBSD?

Question

FreeBSD

Since asking directly to help solve the problem is not comme il faut, I ask you to suggest normal tutorials on writing autorun scripts in Fryakh so that everything is completely chewed.
Preferably in Russian, but not required.

Answer 1

handbook
En
And in Russian

Answer 2

Autorun scripts are written in bash www.bash-scripting.ru/abs/chunks/ , but you can also write in perl or python. The main thing is that the interpreter is on the system. Good luck learning bash
