We just covered files, but what about the directories that hold the files? Permission rights for directories are slightly different than those of files. If a directory has execute permissions turned off, you cannot change into that directory (using the cd command), view its contents, or write to it. It is effectively turned off. If read permissions are turned off, you can still create files in the directory and read them, but you cannot get a listing of what is in the directory. Lastly, if the write permission for a directory is turned off, you can view a listing of the contents and read files, but you cannot create any new files.
