Re: [open-cobol-list] File permissions

Very interesting, but I have nothing to do with IBM's cobol -unless I
love IBM wich support Linux and give me some years ago a T-shirt with
TUX- 
For me the fist problem is depending of what Linux distribution you
use :
- Red-Hat and derived (Mandriva, fedora ...) don't use the group
permission,
the only distro correct for permissions I know is Slackware and
derived (Zenwalk, .. ?)
with this you should not have permission problems if you correctly use
the group permissions and it is not necessary to use a system command :
UNIX/LINUX do that for you.
