General Information
Troubleshooting file permissions issues.
Things to Keep in Mind
Items to keep in mind when troubleshooting file permissions issues.
- Anytime an ACL is updated, the mask changes (max level of permissions changes).
- Group ACL entries do not change when normal group permissions change.
- cp command does not preserve ACL rules, but mv does.
- Default ACL permissions are for inheritance.
Apply execute permissions to directories and sub dirs only
chmod -R g+rwX /mydir
- The capital “X” applies only to directories
- Execute permissions are required to cd into a directory
