Once again Annihilannic, thank you very much.

Your awk solution worked brilliantly.

Is the following understanding of your correct?

Code:
%-14s%-4s

This means a 14character field followed by a 4 character field.



Code:
 
substr($0,5),substr($0,1,4))

This means, the 14 character field of the output file is made up of the substring from position 5 onwards from the input file and the 4 character field of the output file consists of the substring from position 1-4 from the original input file.


Sorry if it's a silly question but I'd much rather learn as I go instead of just blindly copying code without learning anything.
