===== 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
<code bash>
chmod -R g+rwX /mydir
</code>
  * The capital "X" applies only to directories
  * Execute permissions are required to cd into a directory
