du — estimate file space usage
du
[OPTION
...] [FILE
...]
du
[OPTION
...] −−files0−from
=F
Summarize disk usage of each FILE, recursively for directories.
Mandatory arguments to long options are mandatory for short options too.
−−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)
−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
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 STYLE: full−iso, long−iso, iso, +FORMAT FORMAT is interpreted like '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
DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment
variables. Otherwise, units default to 1024 bytes (or 512 if
POSIXLY_CORRECT 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, ... (powers of 1000).
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).
