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.
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.
