I am trying to display df -h command out in proper format, how can I display
each field of each record in a fixed length.

a sample input and output (within the vB codes) would be helpful.

Say your input is

sAGFTaEH fsdjngjgtdjkmh fsdgjrutfdhj fsdghyfjj
FDSHF fsfrgtr grsdht htdh
sAGFTaEH fsdjngjgtdjkmh fsdgjrutfdhj fsdghyfjj
FDSHF fsfrgtr grsdht htdh
sAGFTaEH fsdjngjgtdjkmh fsdgjrutfdhj fsdghyfjj
FDSHF fsfrgtr grsdht htdh

use:

$awk '{printf "%-20s %-20s %-20s %-20s\n",$1,$2,$3,$4}' $INPUT_FILE

and check for yourself !!!!!
