df output

[David Henderson]

Good afternoon!  I am trying to get different output from 'df' by
including the '-k', '-m', etc, however, the output is the same no
matter what is passed.  Am I missing something?  Using BB version
1.24.1.

# df -k /dev/sda1
Filesystem                Size      Used Available Use% Mounted on
/dev/sda1               442.7G    326.0G     94.1G  78% /mnt/DATA

#df -m /dev/sda1
Filesystem                Size      Used Available Use% Mounted on
/dev/sda1               442.7G    326.0G     94.1G  78% /mnt/DATA

#df -P /dev/sda1
Filesystem                Size      Used Available Capacity Mounted on
/dev/sda1               442.7G    326.0G     94.1G  78% /mnt/DATA

Thanks,
Dave
