Multiple groups permission to a directory or files

[Shivkumar]

Hi,

We know that group permission means that member of the group will get same permission as group. If a directory or file has more than one groups then we use newgrp command to get the permission.

My question is there any other way we can assign multiple group permission to a directory or files ?

Thanks,
Shiv

You will find many related commands like the following if you man 'command'. They are listed at the bottome of the man page:

getprivgrp(1), chown(2), getprivgrp(2), lockf(2), plock(2), rtprio(2), rtsched(2), serialize(2), setgid(2), setuid(2), shmctl(2), mpctl(2), pset_create(2), privgrp(4).

Start with setprivgrp and getprivgrp.

The setprivgrp command associates a group with a list of privileges, thus providing access to certain system capabilities for members of a particular group or groups. The privileges can be displayed with the getprivgrp command (see getprivgrp(1)).
