### 17.18 PERMISSIONS ¶

    PERMISSIONS
            FILE=’file_name’
            /PERMISSIONS = {READONLY,WRITEABLE}.

`PERMISSIONS` changes the permissions of a file. There is one mandatory subcommand which specifies the permissions to which the file should be changed. If you set a file’s permission to `READONLY`, then the file will become unwritable either by you or anyone else on the system. If you set the permission to `WRITEABLE`, then the file becomes writeable by you; the permissions afforded to others are unchanged. This command cannot be used if the `SAFER` (see SET) setting is active.
