SYNOPSIS --
|
|
.sp
|
|
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.
|
|
.sp
|
|
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.
|
|
.sp
|
|
Words 1-4 represent the (8-character) file name,
|
|
space padded on the right. These words are not
|
|
necessarily cleared for empty slots.
|
|
.sp
|
|
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".
