DESCRIPTION

12       A  directory  behaves  exactly like an ordinary file, save that no user
13       may write into a directory.  The fact that a file  is  a  directory  is
14       indicated by a bit in the flag word of its i-node entry see, filsys(5).
15       The structure of a directory entry as given in the include file is:

45       By convention, the first two entries in each directory are for `.'  and
46       `..'.   The  first is an entry for the directory itself.  The second is
47       for the parent directory.  The meaning of `..' is modified for the root
48       directory  of  the  master  file system and for the root directories of
49       removable file systems.  In the first case, there is no parent, and  in
50       the  second,  the system does not permit off-device references.  There‐
51       fore in both cases `..' has the same meaning as `.'.
