.SH DESCRIPTION
Estimate file space usage
.SH OPTIONS
.TP
\fB\-\-help\fR
Print help information.
.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 (\*(Aqsparse\*(Aq) 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., \*(Aq\-BM\*(Aq prints sizes in units of 1,048,576 bytes. See SIZE format below.
.TP
\fB\-b\fR, \fB\-\-bytes\fR
equivalent to \*(Aq\-\-apparent\-size \-\-block\-size=1\*(Aq
.TP
\fB\-c\fR, \fB\-\-total\fR
produce a grand total
.TP
\fB\-d\fR, \fB\-\-max\-depth\fR=\fIN\fR
print the total for a directory (or file, with \-\-all) only if it is N or fewer levels below the command line argument;  \-\-max\-depth=0 is the same as \-\-summarize
.TP
\fB\-h\fR, \fB\-\-human\-readable\fR
print sizes in human readable format (e.g., 1K 234M 2G)
.TP
\fB\-\-inodes\fR
list inode usage information instead of block usage like \-\-block\-size=1K
.TP
\fB\-k\fR
like \-\-block\-size=1K
.TP
\fB\-l\fR, \fB\-\-count\-links\fR
count sizes many times if hard linked
.TP
\fB\-L\fR, \fB\-\-dereference\fR
follow all symbolic links
.TP
\fB\-D\fR, \fB\-\-dereference\-args\fR
follow only symlinks that are listed on the command line
.TP
\fB\-P\fR, \fB\-\-no\-dereference\fR
don\*(Aqt follow any symbolic links (this is the default)
.TP
\fB\-m\fR
like \-\-block\-size=1M
.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\-\-si\fR
like \-h, but use powers of 1000 not 1024
.TP
\fB\-x\fR, \fB\-\-one\-file\-system\fR
skip directories on different file systems
.TP
\fB\-t\fR, \fB\-\-threshold\fR=\fISIZE\fR
exclude entries smaller than SIZE if positive, or entries greater than SIZE if negative
.TP
\fB\-v\fR, \fB\-\-verbose\fR
verbose mode (option not present in GNU/Coreutils)
.TP
\fB\-\-exclude\fR=\fIPATTERN\fR
exclude files that match PATTERN
.TP
\fB\-X\fR, \fB\-\-exclude\-from\fR=\fIFILE\fR
exclude files that match any pattern in FILE
.TP
\fB\-\-files0\-from\fR=\fIFILE\fR
summarize device usage of the NUL\-terminated file names specified in file F; if F is \-, then read names from standard input
.TP
\fB\-\-time\fR=\fIWORD\fR
show time of the last modification of any file in the directory, or any of its subdirectories. If WORD is given, show time as WORD instead of modification time: atime, access, use, ctime, status, birth or creation
.br

.br
[\fIpossible values: \fRatime, ctime, creation]
.TP
\fB\-\-time\-style\fR=\fISTYLE\fR
show times using style STYLE: full\-iso, long\-iso, iso, +FORMAT FORMAT is interpreted like \*(Aqdate\*(Aq
.TP
\fB\-V\fR, \fB\-\-version\fR
Print version
.SH EXTRA
Display values are in units of the first available SIZE from \-\-block\-size,
and the DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables.
Otherwise, units default to 1024 bytes (or 512 if POSIXLY_CORRECT is set).

SIZE is an integer and optional unit (example: 10M is 10*1024*1024).
Units are K, M, G, T, P, E, Z, Y (powers of 1024) or KB, MB,... (powers
of 1000).

PATTERN allows some advanced exclusions. For example, the following syntaxes
are supported:
? will match only one character
* will match zero or more characters
{a,b} will match a or b
