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 sys-
tem 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 POSIXLYCORECT 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

resides, or all file systems by default.
Mandatory arguments to long options are mandatory for short
options too.

-h, --human-readable

-i, --inodes

-k like --block-size=1K
-l, --local
