Sharing Files

The login node of the cluster runs a version of the Linux operating system and the usual Linux owner/group/world file protection scheme can be used to protect and/or share files. User accounts for members of a research group are created within a single Linux group to facilitate file sharing. It is also possible for individuals to be members of multiple groups. 

Share the file with your group:

From your home directory (/home/<userid>, create a new directory <share-dir>

mkdir <share-dir>

Share the file only with your group.

chmod -R 770 <share-dir>

Sometimes you may want to change the ownership, 

chown -R <user>:<group> <share-dir>

The group members should be able to have full access at /home/<user>/<share-dir>
