rwxrwxr-xExplanation
chmod 775 gives the owner and group members full read, write, and execute permissions, while others get read and execute only. Suitable for project directories shared among developers in the same group, or team-shared build caches. Enables group collaboration while blocking modification by outsiders.
Common Use Cases
- ▸Team shared project directories (/srv/project)
- ▸Deployment directories shared between web server group and developers
- ▸CI/CD shared artifact directories
- ▸Workspaces for multiple developers under the same group
- ▸Shared virtual environment (venv) directories
Security Considerations
When using 775, combine it with the setgid bit (g+s) so that newly created files inherit the group automatically, making collaboration smoother. Manage group membership carefully and remove unnecessary users from the group. No write access for others makes this far safer than 777.
Command Examples
$ chmod 775 /srv/project$ chmod g+s /srv/project # setgid for group inheritance$ chown -R :developers /srv/project$ find /srv/project -type d -exec chmod 775 {} \;Related Permissions
