NAME
du - estimate file space usage
SYNOPSIS
du [OPTION]... [FILE]...
du [OPTION]... files0-from=F
DESCRIPTION
Summarize disk usage of each FILE, recursively for directories.
Mandatory arguments to long options are mandatory for short options
too.
-0, null
end each output line with 0 byte rather than newline
-a, all
write counts for all files, not just directories
apparent-size
print apparent sizes, rather than disk usage; although the
apparent size is usually smaller, it may be larger due to holes
in ('sparse') files, internal fragmentation, indirect blocks,
and the like
-B, block-size=SIZE
scale sizes by SIZE before printing them; e.g., '-BM' prints
sizes in units of 1,048,576 bytes; see SIZE format below
-b, bytes
equivalent to 'apparent-size block-size=1'
-c, total
produce a grand total
-D, dereference-args
dereference only symlinks that are listed on the command line
-d, max-depth=N
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
files0-from=F
summarize disk usage of the NUL-terminated file names specified
in file F; if F is -, then read names from standard input
-H equivalent to dereference-args (-D)
-h, human-readable
print sizes in human readable format (e.g., 1K 234M 2G)
inodes
list inode usage information instead of block usage
-k like block-size=1K
-L, dereference
dereference all symbolic links
-l, count-links
count sizes many times if hard linked
-m like block-size=1M
-P, no-dereference
don't follow any symbolic links (this is the default)
-S, separate-dirs
for directories do not include size of subdirectories
si like -h, but use powers of 1000 not 1024
-s, summarize
display only a total for each argument
-t, threshold=SIZE
exclude entries smaller than SIZE if positive, or entries
greater than SIZE if negative
time show time of the last modification of any file in the directory,
or any of its subdirectories
time=WORD
show time as WORD instead of modification time: atime, access,
use, ctime or status
time-style=STYLE
show times using STYLE, which can be: full-iso, long-iso, iso,
or +FORMAT; FORMAT is interpreted like in 'date'
-X, exclude-from=FILE
exclude files that match any pattern in FILE
exclude=PATTERN
exclude files that match PATTERN
-x, one-file-system
skip directories on different file systems
help display this help and exit
version
output version information and exit
Display values are in units of the first available SIZE from
block-size, and the DUBLOCKSIZE, BLOCKSIZE and BLOCKSIZE environ‐
ment variables. Otherwise, units default to 1024 bytes (or 512 if
POSIXLYCORRECT 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, ... (pow‐
ers of 1000).

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