[aclug-L] Re: dos file permissions under linux

[John Goerzen <jgoerzen@xxxxxxxxxxxx>]

the short answer: you can't.  DOS does not support permissions.

HOWEVER...

Look at the mount(8) manpage, skip down to the "Mount options for fat" 
section.  Note the uid, gid, and umask items.  These are applicable to 
ALL files in the mounted partition; you cannot apply them to one in
particular.  You can then use a command like:

mount -t vfat -o uid=1000,gid=1000,umask=0002 /dev/hda1 /mnt 

Note that the umask says what NOT to have.  So in this case, only the
world write is denied; either the user with uid 1000 or anyone in
group 1000 will have full access.  You can also specify the option
string in /etc/fstab in the fourth field (where you normally find
"defaults").
