NAME

du − summarize disk usage

SYNOPSIS

du [ −s ] [ −a ] [ name ... ]

DESCRIPTION

Du gives the number of kilobytes contained in all files and, recursively, directories within each specified directory or file name. If name is missing, ‘.’ is used. 

A file which has two links to it is only counted once. 

OPTIONS

−s Only display the grand total. 

−a Generate an entry for each file. 

Entries are generated only for each directory in the absence of options. 

SEE ALSO

df(1), quot(8)

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.
