    Command:

    df

    
    
    

    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 contain-
           ing  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
    
           --direct
                  show statistics for a file instead of mount point
    
           --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
    
           -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 environ-
           ment 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 fol-
           lowing: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T,
           P, E, Z, Y.
