add a single char without over duplicating a string 1

[grazinggoat]

Hello,

I've tried this with (off topic sed) but could not get it to work.
Is the a method in awk so that i can take a line like this:

a ba baa aab ab aaa aa a bab aba

to get this:

aa baa baa aab aab aaa aa aa baab aabaa

basically when ever there is a double aa ignore it
but add a a where it see's a "a"

Any thoughts please?

A starting point:

awk '{for(i=1;i<=NF;++i)if($i!~/aa/)gsub(/a/,"aa",$i);print}' /path/to/input >output

Hope This Helps, PH.
