Exclamation Multiple users.....

OK. Here is scenario:
There is four groups of users : group1, group2 ,group3 and group4
i am creating one folder as root and deciding that file owner is root and file group is group1.
Question is: how i can add group2 to be able to read and write and group3 only read access on that folder? I don't want to group4 be able to access this folder so i can't get read access to 'others'....
This is giving me a big headache, looking for answer for some time and could not found anything...

Thanks in advance!!!!!!!!

You can't, as far as I know. It's not like Windows where you can give multible groups different permissions. This is the only thing that I wish Linux would do like Windows.

I know of no simple way to do this in linux, however someone implemented ACL (access control lists). This might do the job.

From their page:
Access Control Lists (ACLs) support more fine-grained permissions. Arbitrary users and groups can be granted or denied access in addition to the three traditional classes of users. The three classes of users can be regarded as three entries of an Access Control List. Additional entries can be added that define the permissions specific users or groups are granted.
The stuff can be found at
I suggest you read through the stuff and see if it is worth the hassle.
