Users in multiple groups?
Happy Thanksgiving Everyone!! I have a question about adding users to multiple groups. Thanks in advance

Using Red Hat and here are the issues:
Example:

Users:
Bob
Mark

Groups:
SystemsAnalysts
BusinessAnalysts

If I am adding a user Bob to both groups (SystemsAnalysts and BusinessAnalysts)

Code:
usermod -G SystemsAnalysts Bob
usermod -G BusinessAnalysts Bob

Seems to be removing the user Bob from SystemsAnalysts group when I add the user Bob to the BusinessAnalysts group.

Is there a limit of groups a user can be in(assuming no)? Or any ideas why I am running into this issue. The only thing I can think of is maybe it has to do with the directory permissions and the group owner of the directory permissions??? Any help would be greatly appreciated!!

I guess he figured it out reading the usermod manpage:
Quote:
NAME
usermod - modify a user account
...
-G, --groups GROUP1[,GROUP2,...[,GROUPN]]]
A list of supplementary groups which the user is also a member of.
Each group is separated from the next by a comma, with no
intervening whitespace. The groups are subject to the same
restrictions as the group given with the -g option. If the user is
currently a member of a group which is not listed, the user will be
removed from the group. This behaviour can be changed via the -a
option, which appends the user to the current supplementary group
list.
