Hi,

There are a lot of resource about creating Linux daemon. But I am not
sure which is one is the most correct and provide the essential things
for a Linux daemon in bash that can be start/stop by `sudo service`?
Would anybody point me the best resource to learn how to create such a
daemon? Thanks.
