Name
du — estimate file space usage
Synopsis
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 following: 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).
