27 .SH DESCRIPTION
28 .sp
29 .LP
30 The \fBdu\fR utility writes to standard output the size of the file space
31 allocated to, and the size of the file space allocated to each subdirectory of,
32 the file hierarchy rooted in each of the specified files. The size of the file
33 space allocated to a file of type directory is defined as the sum total of
34 space allocated to all files in the file hierarchy rooted in the directory plus
35 the space allocated to the directory itself. This sum will include the space
36 allocated to any extended attributes encountered.
37 .sp
38 .LP
39 Files with multiple links will be counted and written for only one entry. The
40 directory entry that is selected in the report is unspecified. By default, file
41 sizes are written in 512-byte units, rounded up to the next 512-byte unit.
42 .SS "/usr/xpg4/bin/du"
43 .sp
44 .LP
45 When \fBdu\fR cannot obtain file attributes or read directories (see
46 \fBstat\fR(2)), it will report an error condition and the final exit status
47 will be affected.
48 .SH OPTIONS
49 .sp
50 .LP
51 The following options are supported for \fB/usr/bin/du\fR and
52 \fB/usr/xpg4/bin/du\fR:
53 .sp
54 .ne 2
55 .na
56 \fB\fB-a\fR\fR
57 .ad
58 .RS 6n
59 In addition to the default output, report the size of each file not of type
60 directory in the file hierarchy rooted in the specified file. Regardless of the
61 presence of the \fB-a\fR option, non-directories given as \fIfile\fR operands
62 will always be listed.
63 .RE
64
65 .sp
66 .ne 2
67 .na
68 \fB\fB-d\fR\fR
69 .ad
70 .RS 6n
71 Do not cross filesystem boundaries. For example, the command, \fBdu -d /\fR
72 reports usage only on the root partition.
73 .RE
74
75 .sp
76 .ne 2
77 .na
78 \fB\fB-h\fR\fR
79 .ad
80 .RS 6n
81 All sizes are scaled to a human readable format, for example, \fB14K\fR,
82 \fB234M\fR, \fB2.7G\fR, or \fB3.0T\fR. Scaling is done by repetitively dividing
83 by \fB1024\fR.

87 .ne 2

167 When evaluating file sizes, evaluate only those files that have the same device
168 as the file specified by the file operand.
169 .RE
170
171 .sp
172 .LP
173 Specifying more than one of the options in the mutually exclusive pair,
174 \fB-H\fR and \fB-L\fR, is not considered an error. The last option specified
175 determines the output format.
176 .sp
177 .LP
178 Specifying more than one of the options in the mutually exclusive set of
179 options \fB-h\fR, \fB-k\fR, and \fB-m\fR is not considered an error. The last
180 option specified determines the output format.
181 .SH OPERANDS

184 The following operand is supported:
185 .sp
186 .ne 2
187 .na
188 \fB\fIfile\fR\fR
189 .ad
190 .RS 8n
191 The path name of a file whose size is to be written. If no \fIfile\fR is
192 specified, the current directory is used.
193 .RE
194
195 .SH OUTPUT
196 .sp
197 .LP
198 The output from \fBdu\fR consists of the amount of the space allocated to a
199 file and the name of the file.

202 .LP
