linux_file_persmisisons

Under Linux, permissions are assigned to users and groups. Each user can be a member of different groups, and membership in these groups gives the user specific, additional permissions. Each file and directory belongs to a specific user and a specific group. So the permissions for users and groups that defined a file are also defined for the respective owners. When we create new files or directories, they belong to the group we belong to and us.
