DIRECTORY (V)
NAME format of directories
SYNOPSIS
DESCRIPTION A directory behaves exactly like an ordinary file, save
that no user may write into a directory. The fact that a
file is a directory is indicated by a bit in the flag word
of its i-node entry.
Directory entries are 8 words long. The first word is the
i-node of the file represented by the entry, if non-zero;
if zero, the entry is empty.
Words 1-4 represent the (8-character) file name, space
padded on the right. These words are not necessarily
cleared for empty slots.
By convention, the first entry in each directory is
for "dd", which is the "directory directory" that holds
all the users' home directories and the "system" directory.
The "system" directory contains "init" and "sh".
