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

       --total
	      produce a grand total

       -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.
