[root@DIM ~]# df --help
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 dummy file systems
  -B, --block-size=SIZE  use SIZE-byte blocks
  -h, --human-readable  print sizes in human readable format (e.g., 1K 234M 2G)
  -H, --si              likewise, but use powers of 1000 not 1024
  -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)
  -P, --portability     use the POSIX output format
      --sync            invoke sync before getting usage info
  -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

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.

NAME
       df - report file system disk space usage

SYNOPSIS
       df [OPTION]... [FILE]...

DESCRIPTION
       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 (which is always
       the root file system).  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.

OPTIONS
       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 dummy file systems

       -B, --block-size=SIZE
              use SIZE-byte blocks

       -h, --human-readable
              print sizes in human readable format (e.g., 1K 234M 2G)

       -H, --si
              likewise, but use powers of 1000 not 1024

       -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)

       -P, --portability
              use the POSIX output format

       --sync invoke sync before getting usage info

       -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

       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.
