sharing files read only for a group
i have installed redhat enterprise linux 3 on my system. now i want to give
a folder to a group of users where they can make files and read each others files, but cat not write to each others files.
if i give rwxr-x--- on the folder then no one can make files in his folder. and
if i give rwxrwx--- on this folder then any one can write to the files even they don't have write permission on files using :wq!(forcefully)in vi . gedit and other
editors says file is read only and can not write to the file.vi also says that file is read only but write to the file when i use :wq!.
folder owner is root and group is SALES.
all the users have their own private group and have a common group SALES
as their secondary group. i have not implemented SGID bit on that folder.
users umask is 002.
looking forward for response.
