.SH NAME
du \- estimate file space usage

.br
.B du
[\fIOPTION\fR]... \fI--files0-from=F\fR
.SH DESCRIPTION
.\" Add any additional description here
.PP
Summarize disk usage of each FILE, recursively for directories.
.PP
Mandatory arguments to long options are mandatory for short options too.
.TP
\fB\-a\fR, \fB\-\-all\fR
write counts for all files, not just directories
.TP
\fB\-\-apparent\-size\fR
print apparent sizes, rather than disk usage; although
the apparent size is usually smaller, it may be
larger due to holes in (`sparse') files, internal
fragmentation, indirect blocks, and the like
.TP
\fB\-B\fR, \fB\-\-block\-size\fR=\fISIZE\fR
scale sizes by SIZE before printing them.  E.g.,
`\-BM' prints sizes in units of 1,048,576 bytes.
See SIZE format below.
.TP
\fB\-b\fR, \fB\-\-bytes\fR
equivalent to `\-\-apparent\-size \fB\-\-block\-size\fR=\fI1\fR'
.TP
\fB\-c\fR, \fB\-\-total\fR
produce a grand total
.TP
\fB\-D\fR, \fB\-\-dereference\-args\fR
dereference only symlinks that are listed on the
command line
.TP
\fB\-\-files0\-from\fR=\fIF\fR
summarize disk usage of the NUL\-terminated file
names specified in file F;
If F is \- then read names from standard input
.TP
\fB\-H\fR
equivalent to \fB\-\-dereference\-args\fR (\fB\-D\fR)
.TP
\fB\-h\fR, \fB\-\-human\-readable\fR
print sizes in human readable format (e.g., 1K 234M 2G)
.TP
\fB\-\-si\fR
like \fB\-h\fR, but use powers of 1000 not 1024
.TP
\fB\-k\fR
like \fB\-\-block\-size\fR=\fI1K\fR
.TP
\fB\-l\fR, \fB\-\-count\-links\fR
count sizes many times if hard linked
.TP
\fB\-m\fR
like \fB\-\-block\-size\fR=\fI1M\fR
.TP
\fB\-L\fR, \fB\-\-dereference\fR
dereference all symbolic links
.TP
\fB\-P\fR, \fB\-\-no\-dereference\fR
don't follow any symbolic links (this is the default)
.TP
\fB\-0\fR, \fB\-\-null\fR
end each output line with 0 byte rather than newline
.TP
\fB\-S\fR, \fB\-\-separate\-dirs\fR
do not include size of subdirectories
.TP
\fB\-s\fR, \fB\-\-summarize\fR
display only a total for each argument
.TP
\fB\-x\fR, \fB\-\-one\-file\-system\fR
skip directories on different file systems
.TP
\fB\-X\fR, \fB\-\-exclude\-from\fR=\fIFILE\fR
exclude files that match any pattern in FILE
.TP
\fB\-\-exclude\fR=\fIPATTERN\fR
exclude files that match PATTERN
.TP
\fB\-d\fR, \fB\-\-max\-depth\fR=\fIN\fR
print the total for a directory (or file, with \fB\-\-all\fR)
only if it is N or fewer levels below the command
line argument;  \fB\-\-max\-depth\fR=\fI0\fR is the same as
\fB\-\-summarize\fR
.TP
\fB\-\-time\fR
show time of the last modification of any file in the
directory, or any of its subdirectories
.TP
\fB\-\-time\fR=\fIWORD\fR
show time as WORD instead of modification time:
atime, access, use, ctime or status
.TP
\fB\-\-time\-style\fR=\fISTYLE\fR
show times using style STYLE:
full\-iso, long\-iso, iso, +FORMAT
FORMAT is interpreted like `date'
.TP
\fB\-\-help\fR
display this help and exit
.TP
\fB\-\-version\fR
output version information and exit
.PP
Display values are in units of the first available SIZE from \fB\-\-block\-size\fR,
and the DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables.
Otherwise, units default to 1024 bytes (or 512 if POSIXLY_CORRECT is set).
.PP
SIZE may be (or may be an integer optionally followed by) one of following:
KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y.
.SH PATTERNS
PATTERN is a shell pattern (not a regular expression).  The pattern
.BR ?
matches any one character, whereas
.BR *
matches any string (composed of zero, one or multiple characters).  For
example,
.BR *.o
will match any files whose names end in
.BR .o .
Therefore, the command
.IP
.B du --exclude=\(aq*.o\(aq
.PP
will skip all files and subdirectories ending in
.BR .o
(including the file
.BR .o
itself).
