I created a user is john, and his group is business, I found the business group's ID is 500
when I use less /etc/group. but when I use id -g business , it shows "id:business:no such user", and then I run id -u john, it shows 502, why id -g business doesn't work??????????????????????????????

"id" only takes an username as an argument. When you do "id -g business" this will not print the group-ID of the group "business", but it tries to print the (effective) group ID of user "business", which doesn't exist.

Try: id -G john
This will print the groups-ID's user "john" is member of.
