NAME
du - summarize disk usage
SYNOPSIS
du [ -s ] [ -a ] [ name ... ]
DESCRIPTION
Du gives the number of kilobytes (kilo=1024) allocated to data blocks
of named files and of named directories including (recursively) their
contents. If name is missing, `.' is used.
Option -s causes only the grand total to be given. Option -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 counted only once.
SEE ALSO
df(1), quot(8)
BUGS
In the absence of option -a non-directories given as arguments are not
listed.
If there are too many distinct linked files, du counts the excess files
multiply.
Unwritten holes in files count as if real data were present, and indi‐
rect blocks are not counted.
