  47. Command /Qualifier or Keyword Security Information directory /protection Display the UIC protection code /owner Display the owner /security Display all of the above show security Display all of the above protection Display the default protection for process Set security/protection=(code) filespec Control a file’s UIC protection code (ex) Set security/protection = (s:rwe,o:rwe,g,w) sample.file Set protection =(s:rwe,g)/default To change default protection Displaying & Manipulating Files Security Information
