du - estimate file space usage

du [

--files0-from=F
Summarize device 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 device 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 device 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.
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).
