"The -v option is useless with df."
-v option for displaying the used blocks which by default don't show up in df.
-------------------------
Lastly,Will it be correct to say from the following , that :
# du -xk / | tail -1
38195512
# df -k -v
Mount Dir Filesystem blocks used free %used
/ /dev/root 871678974 64231830 807447144 8%
/stand /dev/boot 40959 6413 34546 16%
For my / partition
total partition space (df)= 871678974 blocks = 871.6 gb (approx.)
present used space by whole partition (df -v) = 64231830 blocks= 64.2 gb (approx.)
space usage by files and directories (du) = 38195512 blocks = 38.1 gb (approx.)
space used by filesystem entities/data = 64.2 - 38.1 gb = 26.1 gb (approx.)

NAME
mkfs.bfs - make an SCO bfs filesystem
SYNOPSIS
mkfs.bfs [options] device [block-count]
DESCRIPTION
mkfs.bfs creates an SCO bfs filesystem on a block device (usually a disk partition or a file accessed via the loop device).
The block-count parameter is the desired size of the filesystem, in blocks. If nothing is specified, the entire partition will be used.
OPTIONS
-N, --inodes number
Specify the desired number of inodes (at most 512). If nothing is specified, some default number in the range 48-512 is picked
depending on the size of the partition.
-V, --vname label
Specify the volume label. I have no idea if/where this is used.
-F, --fname name
Specify the filesystem name. I have no idea if/where this is used.
-v, --verbose
Explain what is being done.
-c This option is silently ignored.
-l This option is silently ignored.
-h, --help
Display help text and exit.
-V, --version
Output version information and exit. Option -V only works as --version when it is the only option.
EXIT CODES
The exit code returned by mkfs.bfs is 0 when all went well, and 1 when something went wrong.
SEE ALSO
mkfs(8).
AVAILABILITY
The mkfs.bfs command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
