DU(1)

NAME
du - estimate file space usage

SYNOPSIS
du [OPTION]... [FILE]...
du [OPTION]... --files0-from=F

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).
