DU(1)

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.

-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 use SIZE-byte blocks

-b, --bytes
    equivalent to `--apparent-size --block-size=1'

-c, --total
    produce a grand total

-D, --dereference-args
    dereference FILEs that are symbolic links

--files0-from=F
    summarize disk usage of the NUL-terminated file names specified in file F

-H  like --si, but also evokes a warning; will soon change to be equivalent to --dereference-args (-D)

-h, --human-readable
    print sizes in human readable format (e.g., 1K 234M 2G)

--si
    like -h, but use powers of 1000 not 1024

-k  like --block-size=1K

-l, --count-links
    count sizes many times if hard linked

-L, --dereference
    dereference all symbolic links

-P, --no-dereference
    don't follow any symbolic links (this is the default)

-0, --null
    end each output line with 0 byte rather than newline

-S, --separate-dirs
    do not include size of subdirectories

-s, --summarize
    display only a total for each argument

-x, --one-file-system
    skip directories on different file systems

-X FILE, --exclude-from=FILE
    Exclude files that match any pattern in FILE.

--exclude=PATTERN Exclude files that match PATTERN.

--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

--help
    display this help and exit

--version
    output version information and exit

SIZE may be (or may be an integer optionally followed by) one of following: kB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y.

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).
