Question How you know this file, this permission, this ower, this group?

[AxelKirk]

I'm looking for a better user permission management. I'm on windows, and I have to manage 4 differents server without ubuntu 14, 16. I have learn about usermod/gpasswd and acl. But now I don't know for each file, what should be the permission/group/owner on it ?

How you, adminsys are doing to know each time : this file/folder should belong to this group, this user ... ? Do you have a linux clone which allow you to check how it should be ? Or is there some general rules about it ?

Thanks for your advice, (I have some server where I completly messup the permission with some chmod -R)

Well, It's a very good link. But again, it only deals with how do things but not how things should be ....
