MSI offers the directories /home/group/shared and /home/group/public in the /home/group space for collaboration between group members and those outside of your group. As this is the best storage location, we recommend that you and fellow group members use these directories to share files.
To allow all group members to read/write a specific directory whoever currently owns the files must copy the files to the shared space and run this command in the Linux prompt.
chmod -R g+rwx /home/groupname/shared/filestoshare
If you want all new files you create/copy over to be group read/writable, put this line in your .bashrc:
umask 007
All of your group members should do this, so all your new files are readable/writable by all group members.
To allow non group members to read a specific directory whoever currently owns the files must copy the files to the public space and run this command in the linux prompt.
chmod -R o+rx /home/groupname/public/filestoshare
This will allow users that are not members of your group to have access to your data but they can't write to your public space so as to use up your space.
