    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. --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 


       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. 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).
