Usage: df [OPTION]... [FILE]...

Show information about the file system on which each FILE resides,

or all file systems by default.

Mandatory arguments to long options are mandatory for short options too.

  -a, --all             include pseudo, duplicate, inaccessible file systems

  -B, --block-size=SIZE  scale sizes by SIZE before printing them; e.g.,

                           '-BM' prints sizes in units of ,, bytes;

                           see SIZE format below

  -h, --human-readable  print sizes in powers of  (e.g., 1023M)

  -H, --si              print sizes in powers of  (e.g., .1G)

  -i, --inodes          list inode information instead of block usage

  -k                    like --block-size=1K

  -l, --local           limit listing to local file systems

      --no-sync         do not invoke sync before getting usage info (default)

      --output[=FIELD_LIST]  use the output format defined by FIELD_LIST,

                               or print all fields if FIELD_LIST is omitted.

  -P, --portability     use the POSIX output format

      --sync            invoke sync before getting usage info

      --total           elide all entries insignificant to available space,

                          and produce a grand total

  -t, --type=TYPE       limit listing to file systems of type TYPE

  -T, --print-type      print file system type

  -x, --exclude-type=TYPE   limit listing to file systems not of type TYPE

  -v                    (ignored)

      --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 DF_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables.

Otherwise, units default to  bytes (or  if POSIXLY_CORRECT is set).

The SIZE argument is an integer and optional unit (example: 10K is *).

Units are K,M,G,T,P,E,Z,Y (powers of ) or KB,MB,... (powers of ).

FIELD_LIST is a comma-separated list of columns to be included.  Valid

field names are: 'source', 'fstype', 'itotal', 'iused', 'iavail', 'ipcent',

'size', 'used', 'avail', 'pcent', 'file' and 'target' (see info page).

The SIZE argument is an integer and optional unit (example: 10K is *).

Units are K,M,G,T,P,E,Z,Y (powers of ) or KB,MB,... (powers of ).

Using color to distinguish file types is disabled both by default and

with --color=never.  With --color=auto, ls emits color codes only when

standard output is connected to a terminal.  The LS_COLORS environment

variable can change the settings.  Use the dircolors command to set it.

Exit status:

   if OK,

   if minor problems (e.g., cannot access subdirectory),

   if serious trouble (e.g., cannot access command-line argument).

  -d, --dictionary-order        只考虑空白区域和字母字符

  -f, --ignore-case             忽略字母大小写

  -g, --general-numeric-sort  compare according to general numerical value

  -i, --ignore-nonprinting    consider only printable characters

  -M, --month-sort            compare (unknown) < 'JAN' < ... < 'DEC'

  -h, --human-numeric-sort    使用易读性数字(例如： 2K 1G)

  -n, --numeric-sort            根据字符串数值比较

  -R, --random-sort             根据随机hash 排序

      --random-source=文件      从指定文件中获得随机字节

  -r, --reverse                 逆序输出排序结果

      --sort=WORD               按照WORD 指定的格式排序：

                                        则使用临时文件

  -c, --check, --check=diagnose-first   检查输入是否已排序，若已有序则不进行操作

  -C, --check=quiet, --check=silent     类似-c，但不报告第一个无序行

      --compress-program=程序   使用指定程序压缩临时文件；使用该程序

                                        的-d 参数解压缩文件

KEYDEF is F[.C][OPTS][,F[.C][OPTS]] for start and stop position, where F is a

field number and C a character position in the field; both are origin , and

the stop position defaults to the line's end.  If neither -t nor -b is in

effect, characters in a field are counted from the beginning of the preceding

whitespace.  OPTS is one or more single-letter ordering options [bdfgiMhnRrV],

which override global ordering options for that key.  If no key is given, use

the entire line as the key.

SIZE may be followed by the following multiplicative suffixes:

内存使用率% %，b 、K  (默认)，M、G、T、P、E、Z、Y 等依此类推。

如果不指定文件，或者文件为"-"，则从标准输入读取数据。

*** 警告 ***

本地环境变量会影响排序结果。

如果希望以字节的自然值获得最传统的排序结果，请设置LC_ALL=C。

zebra@ubuntu:~$

zebra@ubuntu:~$ sudo du  --help

用法：du [选项]... [文件]...

　或：du [选项]... --files0-from=F

Summarize disk usage of each FILE, recursively for directories.

必选参数对长短选项同时适用。

  -, --null            end each output line with  byte rather than 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 ,, 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= 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)

  -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   do not include size of subdirectories

      --si              like -h, but use powers of  not

  -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 STYLE:

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

                          FORMAT is interpreted like '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  字节(或是 ，若设定 POSIXLY_CORRECT 的话)。

SIZE is an integer and optional unit (example: 10M is **).  Units

are K, M, G, T, P, E, Z, Y (powers of ) or KB, MB, ... (powers of ).
