Korn: How to zero fill df output so it will sort properly
I'm looking for a way in Korn shell to zero fill (or space fill) the output from df so that it will sort properly.

"Raw" output from df -k:

Code:
df -k

Filesystem            kbytes    used   avail capacity  Mounted on
/dev/vx/dsk/rootvol  4131866 3593302  497246    88%    /

fd                         0       0       0     0%    /dev/fd

                     1047527424 60483821 925353439     7%    /s03

Sorted df output (which incorrectly sorts 28% and 27% after 7%):

Code:
df -k | grep / | awk '{ print $5}' | sort -r

92%
88%
7%
6%
6%
28%
27%
1%
1%
0%
0%
0%

I would like the output to display in the following format:

Code:
92%
88%
28%
27%
 7%
 6%
 6%
 1%
 1%
 0%
 0%
 0%

Any ideas?

NAME

       mkdevmaps - make device_maps entries

SYNOPSIS

       /usr/sbin/mkdevmaps

DESCRIPTION

       The  mkdevmaps  command  writes  to standard out a set of device_maps(4) entries describing the system's frame buffer, audio, and removable
       media devices.

       The mkdevmaps command is used by the init.d(4) scripts to create or update the /etc/security/device_maps file.

       Entries are generated based on the device special files found in /dev. For the different  categories  of  devices,  the  mkdevmaps  command
       checks for the following files under /dev:

       audio           /dev/audio, /dev/audioctl, /dev/sound/...
       tape            /dev/rst*, /dev/nrst*, /dev/rmt/...
       floppy          /dev/diskette, /dev/fd*, /dev/rdiskette, /dev/rfd*
       removable disk  /dev/dsk/c0t?d0s?, /dev/rdsk/c0t?d0s?
       frame buffer    /dev/fb
