Power Here is one approach, and it combines a couple different tricks

Code:
> cat inputf
15% /
0% /devices
0% /system/contract
0% /proc
0% /etc/mnttab
1% /etc/svc/volatile
0% /system/object
0% /dev/fd
1% /var/run
50% /s01
40% /s02
20% /u01

Code:
> cat scan_data 
#! /bin/bash
while read zf
   do
   numb=$(echo "$zf" | cut -d"%" -f1)
   driv=$(echo "$zf" | cut -d"%" -f2)

   drivt=$(printf "%-40s" "$driv")
   numbt=$(printf "%9.3f" "$numb")
   echo "For your disk drive = $drivt ... your percentage full is $numbt"

done<inputf

Code:
> scan_data 
For your disk drive =  /                                       ... your percentage full is    15.000
For your disk drive =  /devices                                ... your percentage full is     0.000
For your disk drive =  /system/contract                        ... your percentage full is     0.000
For your disk drive =  /proc                                   ... your percentage full is     0.000
For your disk drive =  /etc/mnttab                             ... your percentage full is     0.000
For your disk drive =  /etc/svc/volatile                       ... your percentage full is     1.000
For your disk drive =  /system/object                          ... your percentage full is     0.000
For your disk drive =  /dev/fd                                 ... your percentage full is     0.000
For your disk drive =  /var/run                                ... your percentage full is     1.000
For your disk drive =  /s01                                    ... your percentage full is    50.000
For your disk drive =  /s02                                    ... your percentage full is    40.000
For your disk drive =  /u01                                    ... your percentage full is    20.000
For your disk drive =                                          ... your percentage full is     0.000

df(1)							      General Commands Manual							     df(1)

Name
       df - display free and used disk space

Syntax
       df [-i] [-l] [-n] [filesystem...] [file...]

Description
       The command displays the amount of disk space available on the specified file system, for example, It also displays the amount of available
       disk space on the file system in which the specified file is contained, for example, If a device is given that has no file systems  mounted
       on  it,	displays  the  information  for  the  root file system.  Without any arguments or options, displays shows all mounted filesystems,
       including those manually mounted without use of the file.  The numbers are reported in kilobytes.

       Unless the -n option is specified, updates the statistics stored in memory for the file system specified, before it  returns  the  informa-
       tion.

Options
       -i   Also report the number of used and free inodes.

       -l   Reports on locally mounted disks only.

       -n   Do	not  update the file system statistics stored in memory.  Instead, return whatever statistics are stored in memory.  This prevents
	    from hanging in the event that a server containing the specified file system is down.

Restrictions
       You cannot use the command to find free space on an unmounted file system using the block or character special device name.   Instead,  use
       the command.

Examples
       % df
       Filesystem     Total    kbytes  kbytes	%
       node	      kbytes   used    free	used	Mounted on
       /dev/ra1a       7429    2085    4602	31%    /tmp
       /dev/ra0e      30519   14817   12651	54%    /usr/spool
       /dev/ra0h     313233  122858  159052	44%    /usr/staff1

       The  total  disk  space is the total space that was created during the making of the file system.  The addition of the used space, the free
       space and a percentage of reserved space is the total space.  The default value for the reserved space is 10%.

Files
       List of mounted file systems
