Thanks for A.J. Venter. But, as for restrict access to groups, I have a more complicated question: If I have 6 groups of user. The group names are: sec1, sec2, sec3, sec4, admin1, admin2. Each group includes many member users. And I have 3 applications. say, 1. /usr/bin/evolution, 2. /usr/bin/mozilla 3. /usr/bin/vim I want applications /usr/bin/evolution /usr/bin/mozilla/ to be available to all member users in sec1, sec2, sec3, sec4; and all above 3 applications available to member users in admin1, admin2 groups. That is to say, that I want to give access of some application program to multiple groups. How can we do this in Linux/Unix? Dongsheng "A.J.
