# du命令 #

# 用法 #

>du --help
    用法：du [选项]... [文件]...
    　或：du [选项]... --files0-from=F
    Summarize disk usage of the set of FILEs, recursively for directories.
    
    必选参数对长短选项同时适用。
      -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		显示此帮助信息并退出
          --version		显示版本信息并退出
    
    所显示的数值是来自 --block-size、DU_BLOCK_SIZE、BLOCK_SIZE 
    及 BLOCKSIZE 环境变量中第一个可用的 SIZE 单位。
    否则，默认单位是 1024 字节(或是 512，若设定 POSIXLY_CORRECT 的话)。
    
    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).
