    du - estimate file space usage


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


    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
    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
    summarize disk usage of the NUL-terminated file names specified in file F
    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)
    like -h, but use powers of 1000 not 1024
    like --block-size=1K
    -l, --count-links
    count sizes many times if hard linked
    like --block-size=1M
    -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.
    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
    show time of the last modification of any file in the directory, or any of its subdirectories
    show time as WORD instead of modification time: atime, access, use, ctime or status
    --time-style=STYLE show times using style STYLE:
    full-iso, long-iso, iso, +FORMAT FORMAT is interpreted like `date'
    display this help and exit
    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.  


    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).
