how to create directory as specified group.

[szhiyong]

Hi,

I have one user called "neurousr", its primary group is users, it also belongs to additional groups such as sys and usrers.

Would someone please tell how neurousr to create a directory as members of sys? For example, neurousr create one directory "/usr4", the result of "ls -l" is:
usr4 neurousr sys

Hi,

$ chgrp /usr4 sys

Hope this helps. Regards.

The directory will be created with permissions of user:primary group.

Sof if the user has a primary group of sys the directory will be created with those permissions. If it is not, you will need to change it with the 'chgrp' command.

As user "neurousr" run the command "newgrp" ..
$ newgrp sys
.. to switch group ownership to "sys". Now the "mkdir" command and you should see the group ownership will be owned by "sys".

Hi,

Thanks a lot.

The newgrp and chgrp all works. I try to mount /dev/vg01/lvxxx /usr4. Then I "ls -l", I found the result is changed:
/usr4 root root

Would someone tell me how to make it as " /usr4 neurousr root" after mounting?

Thanks a lot again.

Hi,
First mount the user4 then do chgrp.
It will be alright.

There is no point doing this because if this mount point is defined in /etc/fstab and the system reboots no matter what ownership you set for your mountpoint directory /usr4 it'll be changed to root:root everytime /usr is remounted. You should leave the ownership of the mount point as it is. Do not try to change it. Whatever permission/ownership for the subdirectories in /usr4 can be manipulated to your liking but not the mountpoint.

[S.K. Chan]

Apparently I was thinking NFS mounts. Obviously that does not apply to local mounts because root can definately change ownership of a local mount point, not necessarily true for remote mounting. So after you hav mounted it, simply change the ownership like suggested and subsequent mount will retain the directory ownership.

Hi,

Thanks a lot for those good way of solving problem.

I used "change ownership" to solve it.
