每天一个linux命令系列——DU

Usage: du [OPTION]... [FILE]...

  or:  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

      --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 only symlinks that are listed on the

                          command line

      --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)

      --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

  -m                    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, --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

      --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 STYLE:

                          full-iso, long-iso, iso, +FORMAT

                          FORMAT is interpreted like `date'

      --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).

 

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.
