How to find out members of groups?

How do I find out the members of a group?

I'm asking because the following shows user valiant$ to have a primary group called machines. But when I look in /etc/group, valiant$ isn't listed as a member of group machines.

Code:

[root@fedora ~]# id valiant$
uid=503(valiant$) gid=505(machines) groups=505(machines)

[root@fedora ~]# grep machines /etc/group
machines:x:505:

Thanks,
Steve

Hi,

machines is that users primary group (gid=505(machines)), only the 'extra' groups that is/are assosited with that user are shown in /etc/group.

id includes the primary group when it shows all the groups that user belongs to. In the above example, the user is only associated with one group (its primary group: machines).

/etc/passwd holds the users primary group (id, not the name) and /etc/group holds all the extra groups a user is assosiated with.

Hope this helps.
