A few questions first:-
  • Would you want this coded in shell script entirely so you could add more things into the loop, or would an awk one-liner be okay?
  • Do you have data in fixed width columns? If so, what are the requirements?
  • What OS are you using? Some commands can be flavour or even version specific.
  • What shell are you using? ksh, bash, csh perhaps?
  • Why does the row starting D not have an 8 in Col4?
Okay, ignore that last one.

I'm trying to understand if you want to have a one-off conversion of the file or are you wanting to perform some action using the data on each line as you go.


Thanks, in advance,
