Man du

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.

-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

use SIZE-byte blocks

-b, –bytes

equivalent to ‘–apparent-size –block-size=1’

-c, –total

produce a grand total

-D, –dereference-args

dereference FILEs that are symbolic links

–files0-from=F

summarize disk usage of the NUL-terminated file names specified
in file F

-H

like –si, but also evokes a warning; will soon change to be
equivalent to –dereference-args (-D)

-h, –human-readable

print sizes in human readable format (e.g., 1K 234M 2G)

–si

like -h, but use powers of 1000 not 1024

-k

like –block-size=1K

-l, –count-links

count sizes many times if hard linked

-m

like –block-size=1M

-L, –dereference

dereference all symbolic links

-P, –no-dereference

don’t follow any symbolic links (this is the default)

-0, –null

end each output line with 0 byte rather than newline

-S, –separate-dirs

do not include size of subdirectories

-s, –summarize

display only a total for each argument

-x, –one-file-system

skip directories on different file systems

-X FILE, –exclude-from=FILE

Exclude files that match any pattern in FILE.

–exclude=PATTERN

Exclude files that match PATTERN.

–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

–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 STYLE:
full-iso, long-iso, iso, +FORMAT FORMAT is interpreted like
‘date’

–help

display this help and exit

–version

output version information and exit

SIZE may be (or may be an integer optionally followed by) one of fol-
lowing: kB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T,
P, E, Z, Y.

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

will skip all files and subdirectories ending in .o (including the file
.o itself).
