NAME

6       du - estimate file space usage

SYNOPSIS

9       du [OPTION]... [FILE]...
10       du [OPTION]... --files0-from=F
11

DESCRIPTION

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

PATTERNS

112       PATTERN is a shell pattern (not a regular expression).  The  pattern  ?
113       matches  any  one  character, whereas * matches any string (composed of
114       zero, one or multiple characters).  For example,  *.o  will  match  any
115       files whose names end in .o.  Therefore, the command
116
117              du --exclude='*.o'
118
119       will skip all files and subdirectories ending in .o (including the file
120       .o itself).
