DU(1) DU(1)
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 gen-
erated 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.
BUGS
Non-directories given as arguments (not under -a option) are
not listed.
If there are too many distinct linked files, du counts the
excess files multiply.
