All,
   
  I have racked my 
  brains trying to figure out a way to insert
  a column of 
  white space in a plain text file several (tens of)
  thousands 
  lines 
  long.  The problem is there is no common text
  before or after 
  the column I need to insert the blank space.
   
  For example, 
  take the following block of text:
   
  12345ABCDE67890FGHJK
  Q1W2E3R4T5Y6U7I8O9P0
  MNBHGVFRT7352508HY7S
  THISLINEHASNOBLANKS2
  ANOTHERLINEWITHNONE5
  1MORELINEWITHNONEZZZ
   
  I would like to 
  insert a column (or two) of white space to
  essentially 
  create fields to be manipulated with NAWK, so
  that the above 
  text would look like the following:
   
  
  12345AB 
  CDE67890F GHJK
  Q1W2E3R 
  4T5Y6U7I8 O9P0
  MNBHGVF 
  RT7352508 HY7S
  THISLIN 
  EHASNOBLA NKS2
  ANOTHER 
  LINEWITHN ONE5
  1MORELI 
  NEWITHNON EZZZ
   
  I can use PERL, if 
  necessary, but have a preference for either a shell script or SED command, 
  etc..
   
  Any 
  ideas?
  
Thanks in 
  advance,
  
Tyler
