NAME

    du -  summarize disk usage

SYNOPSIS

    du [ -s ] [ -a ] [ name ... ]

DESCRIPTION

    _D_u gives the number of blocks contained in all files and
    (recursively) directories within each specified directory or
    file _n_a_m_e.  If _n_a_m_e 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, _d_u counts the
    excess files multiply.
