20 of a file. To enter the command, type <command>attr</command> followed by the |
| 133 | 21 pathlist for the file who's security permissions are to be changed, |
| 22 followed by a list of permissions which are to be turned on or off. | |
| 23 A permission is turned on by giving its abbreviation, or turned off | |
| 24 by preceding its abbreviation with a minus sign. Permissions not | |
| 25 explicitly named are not affected. If no permissions are given the | |
| 26 current file attributes will be printed. You can not change the | |
| 27 attributes of a file which you do not own (except for user zero, who | |
| 28 can change the attributes of any file in the system). | |

45 The <command>attr</command> command may be used to change a directory file to a |
| 133 | 46 non-directory file if all entries have been deleted from it. Since the |
| 47 DEL command will only delete non-directory files, this is the only | |
| 48 way a directory may be deleted. You cannot change a non-directory | |
| 1093 | 49 file to a directory file with this command (see <command>makdir</command>). |
