I am constantly getting confused about the "r" and "x" access bits on a directory. Unless I am off again, the "r" bit allows me to sequentially read the contents of a directory (like reading a sequential text file, sort of). The "x bit allows me to "search" a directory for a specific file name (like doing a keyed read on an ISAM type file). In any case, is there any real reason why I would have an "r" and not an "x" or vice versa? Does an "r" allow me to list the files in a directory, but not open any of them? I.e. do I need "x" authority in a directory to read a file contained in that directory? As you can see, I am confused.
