init.d中的Shell脚本无法在启动时启动

Question

我必须创建一个在启动时启动的魔鬼。它当前位于/etc/init.d中，并且由于我的运行级别是5，所以我已经在/etc/rc5.d中创建了一个符号链接，但是脚本的“启动”情况在启动期间不会启动。我究竟做错了什么？我可以尝试与init.d不同的东西吗？ 预先感谢

            sleep 3
        else
            sleep 1
            echo $$ > devil.pid
            echo "$datee Running service with PID: $cato" >> devil.log
