名称

       df - 报告文件系统磁盘空间使用情况

概述

       df [选项列表]... [文件列表]...

描述

       This  manual page documents the GNU version of df.  df displays the amount of disk space available on the
       file system containing each file name argument.  If no file name is given, the  space  available  on  all
       currently  mounted  file  systems  is  shown.   Disk  space  is shown in 1K blocks by default, unless the
       environment variable POSIXLY_CORRECT is set, in which case 512-byte blocks are used.

       If an argument is the absolute file name of a disk device node containing a mounted file system, df shows
       the space available on that file system rather than on the file system containing the device node.   This
       version of df cannot show the space available on unmounted file systems, because on most kinds of systems
       doing so requires very nonportable intimate knowledge of file system structures.

选项

       显示文件列表中每一个文件所在的文件系统的信息,没有指定文件则默认为整个文件系统。

       必选参数对长短选项同时适用。

       -a, --all
              包含伪(pseudo)、重复和无法访问的文件系统

       -B, --block-size=大小
              scale  sizes  by  SIZE before printing them; e.g., '-BM' prints sizes in units of 1,048,576 bytes;
              see SIZE format below

       -h, --human-readable
              以 1024 为幂显示大小(例如,1023M)

       -H, --si
              以 1000 为幂输出大小(例,1.1G)

       -i, --inodes
              显示 inode 信息而非块使用量

       -k     类似于 --block-size=1K

       -l, --local
              仅列出本地的文件系统

       --no-sync
              取得使用量数据前不进行同步动作(默认)

       --output[=域列表]
              使用域列表定义的输出格式,如果不指定域列表,则输出所有域

       -P, --portability
              使用 POSIX 输出格式

       --sync 取得使用量数据前先进行同步(sync)

       --total
              elide all entries insignificant to available space, and produce a grand total

       -t, --type=类型
              只显示指定文件系统为指定类型的信息

       -T, --print-type
              显示文件系统类型

       -x, --exclude-type=类型
              只显示不是指定类型的文件系统的信息

       -v     (被忽略的选项)

       --help 显示此帮助信息并退出

       --version
              显示版本信息并退出

       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 1024 bytes (or 512 if
       POSIXLY_CORRECT is set).

       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).  Binary prefixes can be used, too: KiB=K, MiB=M, and so
       on.

       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).
