DF(C) XENIX System V DF(C)
Name
df - Report number of free disk blocks.
Syntax
df [ -t ] [ -f ] [ -v -i ] [ file-systems ]
Description
df prints out the number of free blocks and free inodes
available for on-line file systems by examining the counts
kept in the super-blocks; file-systems may be specified by
device name (e.g., /dev/root). If the file-systems argument
is unspecified, the free space on all of the mounted file
systems is sent to the standard output. The list of mounted
file systems is given in /etc/mnttab.
Options include:
-t Causes total allocated block figures to be reported as
well as number of free blocks.
-f Reports only an actual count of the blocks in the free
list (free inodes are not reported). With this option,
df reports on raw devices.
-v Reports the percent of blocks used as well as the
number of blocks used and free.
-i Reports the percent of inodes used as well as the
number of inodes used and free. Use the -i option with
the -v option to display counts of blocks and inodes
free as well as the percentage of inodes and blocks
used.
The -v and -i options can not be used with other df options.

Notes
See Notes under mount(C).
This utility reports sizes in 512 byte blocks. On systems
which use 1024 byte blocks, this means a file of 500 bytes
uses 2 blocks. df will report 2 blocks less free space,
rather than 1 block, since the file uses one system block of
1024 bytes. Refer to the machine(HW) manual page for the
block size used by your system.
