How Effective Permissions are Determined

Linux determines a user's effective permissions based on whether they are the file owner, belong to the file's group (primary or supplementary), or are considered "others". This tool helps you visualize which permission applies.

Tips & Best Practices

  • Remember that ACLs and special bits (setuid/setgid/sticky) can further affect access.
  • Use id command to check a user's groups.
  • Effective permissions are the most permissive of all applicable rules (user > group > others).
