NAME
du - estimate file space usage
SYNOPSIS
du [OPTION]... [FILE]...
du [OPTION]... --files0-from=F
DESCRIPTION
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,R,Q (pow‐
ers 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).
