By default, HPRC accounts are created so that only the owner can read and/or write (inc. modify) files. Owners may relax these permissions - an action that could require HPC staff actions.
Before making such changes, be aware of the following :
- All HPC users are members of the
hpc-users group. For most people, this is their primary group. - Groups can be created for your internal data sharing requirements. You can request to have your primary group changed, but each account only has 1 primary group.
- Giving other people read access to your files means that they can copy your files elsewhere.
- Giving other people write access to your files mean that they can create/delete/modify files in your directory/directories.
- HPC houses too much data to back it up - we cannot revert/roll-back to a previous version of your file(s).
In summary, think very carefully before giving others write access to your HPC home directory.
