Имя (Name)
du - estimate file space usage
Синопсис (Synopsis)
du
[OPTION]... [FILE]...
du
[OPTION]... --files0-from=F
Описание (Description)
Summarize disk usage of the set of FILEs, recursively for
directories.
Mandatory arguments to long options are mandatory for short
options too.
-0
, --null
end each output line with NUL, not 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 DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE
environment variables. Otherwise, units default to 1024 bytes
(or 512 if POSIXLY_CORRECT is set).
The SIZE argument is an integer and optional unit (example: 10K
is 10*1024). Units are K,M,G,T,P,E,Z,Y (powers of 1024) or
KB,MB,... (powers of 1000). Binary prefixes can be used, too:
KiB=K, MiB=M, and so on.
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).
