NAME

6       du - estimate file space usage

SYNOPSIS

9       du [OPTION]... [FILE]...
10       du [OPTION]... --files0-from=F

DESCRIPTION

13       Summarize disk usage of the set of FILEs, 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 NUL, not 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  ap‐
26              parent size is usually smaller, it may be larger due to holes in
27              ('sparse') files, internal fragmentation, indirect  blocks,  and
28              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       The SIZE argument is an integer and  optional  unit  (example:  10K  is
116       10*1024).   Units  are  K,M,G,T,P,E,Z,Y  (powers  of 1024) or KB,MB,...
117       (powers of 1000).  Binary prefixes can be used, too: KiB=K, MiB=M,  and
118       so on.
119

PATTERNS

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