linux中查看文件或者目录大小

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.
