help with permissions without using ACLs

[jturner2121]

hey, im pretty new to linux and this is my problem

i have a directory called test and two groups called teachers and students.

the teachers group has to have read write and execute permissions for the directory test, while the group students can only have read access

and i cant use ACLs to make this happen so if anyone has any links or any information on how to accomplish this it would be greatly appreciated

Thank you =]

This is a homework assignment? Homework questions are not allowed on this forum, so no one will give you an answer.

However, I am more than happy to help explain UNIX permissions. And for those, I suggest you to use the below:

Wikipedia has a good article on UNIX permissions:
File system permissions - Wikipedia, the free encyclopedia

I also wrote a post on this topic that I feel is pretty good at:

Hopefully these will help.

If that is the case, and since you perfectly understand that you need two groups, and the permissions for each of them, you just need to know that you can use chown to change the owner and group for a file, chmod to adjust the permissions, and usermod to add a given user to a group.

You don't need anything else. Read the man pages for those tools and if you can't understand anything, you can come back and ask a more specific question.
