NAME

du - estimate file space usage

SYNOPSIS

du [OPTION]... [FILE]...
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.

-0, --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)
--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).

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).

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).
