[
.B \-i
] [
.B \-l
] [ filesystem ... ] [ file ... ]
.SH DESCRIPTION
.I Df
prints out the number of free blocks
available on the specified
.I filesystem,
e.g. ``/dev/rp0a'',
or on the filesystem in which the specified
.I file,

is contained.
If no file system is specified,
the free space on all of
the normally mounted file systems
is printed.

The reported numbers are in file system block units; currently each filesystem
block is 1024 bytes long, twice the size of the blocks reported by

or
.IR ls (1)
with the

option.
