Converting a string to a pathname 2

[630111]

Greetings!

I've had a request to convert something like this

00054WNGB398977DS

to this \00054\WNGB3\98977.DS

I suppose it would be easy enough to do it by hand, but I have to do it 2625 times! What utility would I use, and what syntax?

I'm guessing every string is consistent. For sure, there is a dot before the last two characters. I'm guessing it's a pattern like backslash, go forward five characters, insert a backslash, go forward five characters, insert a backslash, go forward 5 characters, insert a dot.

Thanks!

echo '00054WNGB398977DS' | nawk -f 630111.awk

here's the 630111.awk

BEGIN {
  step=5
  SLASH="\\"
  DOT="."
}
{
  new=""
  len=length($0)
  for(i=1; i < len; i=i+step) {
     new= ((i==1) ? "" : new ((i+step > len) ? DOT : SLASH) ) substr($0,i, step);
  }
  print new
}
