11/3/71 DU (I)
NAME du -- summarize disk usage
SYNOPSIS du [ -s ] [ -a ] [ name ... ]
DESCRIPTION du gives the number of blocks contained in all
files and (recursively) directories within each
specified directory or file name. If name is
missing, . is used.
The optional argument -s causes only the grand
total to be given. The optional argument -a
causes an entry to be generated for each file.
Absence of either causes an entry to be generated
for each directory only.
A file which has two links to it is only counted
once.

DIAGNOSTICS --
BUGS Files at the top level (not under -a option) are
not listed.
Removable file systems do not work correctly
since i-numbers may be repeated while the corre-
sponding files are distinct. Du should maintain
an i-number list per root directory encountered.
