Hi

I just mounted my windows partition(FAT32) onto Linux , but how do I make my 'guest' account have the rwx rights to the windows directory/partition as root?

Thank you!

Let's say the windows partition is mounted at /mnt/windows. To give all users who are members of the users group the rwx permissions, as root issue the command:
chmod -R g +rwx /mnt/windows

If you want only one user to have such access (other than root), create a new group, and add the guest name to that group. Then change the group ownership of /mnt/windows to the new group.
Use the command:
chgrp -R <newgroup name> /mnt/windows

The -R makes the change recursive throughout /mnt/windows.

Hi

it says:
[root@Red_Hat_LInux mnt]# chmod -R g +rwx /mnt/windows/
chmod: invalid mode string: `g'

and when I try
[root@Red_Hat_LInux mnt]# chmod -R -g +rwx /mnt/windows/
it shows a list of window files:

etc.?

ok got it, it should be:
[root@Red_Hat_LInux]# chmod -R g+rwx /mnt/windows/

but it still gives me a list of files with operation not permitted:
