df



SYNOPSIS

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


DESCRIPTION

       This manual page documents the GNU version of df.  df dis­
       plays the amount of disk space available on the filesystem
       containing  each  file  name argument.  If no file name is
       given,  the  space  available  on  all  currently  mounted
       filesystems 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 filesystem, df shows  the  space
       available on that filesystem rather than on the filesystem
       containing the device  node  (which  is  always  the  root
       filesystem).   This  version  of  df cannot show the space
       available on unmounted filesystems, because on most  kinds
       of  systems  doing  so  requires very nonportable intimate
       knowledge of filesystem structures.


OPTIONS

       Show information about the filesystem on which  each  FILE
       resides, or all filesystems by default.

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

       -a, --all
              include filesystems having 0 blocks

       -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 filesystems

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

       -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  1,000,000, M
       1,048,576, and so on for G, T, P, E, Z, Y.
