1DU(1) User Commands DU(1)
2
3
4
6 du - estimate file space usage
7
9 du [OPTION]... [FILE]...
10 du [OPTION]... --files0-from=F
11
13 Summarize disk usage of each FILE, recursively for directories.
14
15 Mandatory arguments to long options are mandatory for short options
16 too.
17
18 -0, --null
19 end each output line with 0 byte rather than newline
20
21 -a, --all
22 write counts for all files, not just directories
23
24 --apparent-size
25 print apparent sizes, rather than disk usage; although the
26 apparent size is usually smaller, it may be larger due to holes
27 in ('sparse') files, internal fragmentation, indirect blocks,
28 and the like
29
30 -B, --block-size=SIZE
31 scale sizes by SIZE before printing them; e.g., '-BM' prints
32 sizes in units of 1,048,576 bytes; see SIZE format below
33
34 -b, --bytes
35 equivalent to '--apparent-size --block-size=1'
36
37 -c, --total
38 produce a grand total
39
40 -D, --dereference-args
41 dereference only symlinks that are listed on the command line
42
43 -d, --max-depth=N
44 print the total for a directory (or file, with --all) only if it
45 is N or fewer levels below the command line argument;
46 --max-depth=0 is the same as --summarize
47
48 --files0-from=F
49 summarize disk usage of the NUL-terminated file names specified
50 in file F; if F is -, then read names from standard input
51
52 -H equivalent to --dereference-args (-D)
53
54 -h, --human-readable
55 print sizes in human readable format (e.g., 1K 234M 2G)
56
57 --inodes
58 list inode usage information instead of block usage
59
60 -k like --block-size=1K
61
62 -L, --dereference
63 dereference all symbolic links
64
65 -l, --count-links
66 count sizes many times if hard linked
67
68 -m like --block-size=1M
69
70 -P, --no-dereference
71 don't follow any symbolic links (this is the default)
72
73 -S, --separate-dirs
74 for directories do not include size of subdirectories
75
76 --si like -h, but use powers of 1000 not 1024
77
78 -s, --summarize
79 display only a total for each argument
80
81 -t, --threshold=SIZE
82 exclude entries smaller than SIZE if positive, or entries
83 greater than SIZE if negative
84
85 --time show time of the last modification of any file in the directory,
86 or any of its subdirectories
87
88 --time=WORD
89 show time as WORD instead of modification time: atime, access,
90 use, ctime or status
91
92 --time-style=STYLE
93 show times using STYLE, which can be: full-iso, long-iso, iso,
94 or +FORMAT; FORMAT is interpreted like in 'date'
95
96 -X, --exclude-from=FILE
97 exclude files that match any pattern in FILE
98
99 --exclude=PATTERN
100 exclude files that match PATTERN
101
102 -x, --one-file-system
103 skip directories on different file systems
104
105 --help display this help and exit
106
107 --version
108 output version information and exit
109
110 Display values are in units of the first available SIZE from
111 --block-size, and the DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environ‐
112 ment variables. Otherwise, units default to 1024 bytes (or 512 if
113 POSIXLY_CORRECT is set).
114
115 SIZE is an integer and optional unit (example: 10M is 10*1024*1024).
116 Units are K, M, G, T, P, E, Z, Y (powers of 1024) or KB, MB, ... (pow‐
117 ers of 1000).

121
123 PATTERN is a shell pattern (not a regular expression). The pattern ?
124 matches any one character, whereas * matches any string (composed of
125 zero, one or multiple characters). For example, *.o will match any
126 files whose names end in .o. Therefore, the command
127
128 du --exclude='*.o'
129
130 will skip all files and subdirectories ending in .o (including the file
131 .o itself).
