I need for your help !!
In our big team, working under UNIX, we have some UNIX groups.
I want that, for a project name (for example unix account= prj0, group= prj0_access and team1_access)
+ the owner prj0 is able to read/write/execute files in prj0
+ all the UNIX account with the group prj0_access are able to read/write/execute files in prj0
+ all the UNIX account with the group team1_access are able to read/execute files in prj0
+ all the other accounts (in the other UNIX group) are not able to read/execute files in prj0


How can I do that ?

Thank you for your help.
