Diagnose And Correct File Permission Problems

General Information

About this page/how-to/script.


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
  • Execute permissions are required to cd into a directory
