A problem with UNIX users groups


Hi

I am using UNIX shells on a Macintosh.
I would like to :
- Create a new user group
- Define myself as a member of this group
- Modify the group of some files and directories to this new group

I modified the /etc/group, adding this line:
cvs_group:*:600p,cvsuser

pp is my login and cvsuser is another account on the Macintosh.

Then I tried to change the group of a directory and its content.
I used the following command:
Bash$ chgrp -R 600 <directory_path>

But I was prompted the following message:
chgrp: you are not a member of group 600

And my directory and its included files and subdirectories were set to group "admin".

Does anybody know why this happened and how I could become a member of my new group.

Thanks for your help

PEDROSAN

Ok, I use spaces but there should not be any. It is just to disable the smiley:

cvs_group:*:600 : pp,cvsuser

I'm going to take something of a wild guess here since I know next to zilch about Mac OS X. I do know, however, that for user and group management it does not use the standard Unix files (/etc/passwd and /etc/group), but uses something called the Netinfo Database. Therefore, modifying the /etc/group file may not actually do anything. Probably the easiest way to do this is just go through the Apple GUI or Google on Netinfo database. I know there are command line tools for manipulating it, but I have no idea how to use them.

Thanks a lot btmiller.

I finally found the solution. If anybody wanna know how to create or modify a group on Mac OS X just search for "Netinfo Manager" in the following page:
http://developer.apple.com/internet/...soverview.html
Everything is clearly explained.

Good luck
