Here's a Perl regexical way: s/(.)(.)/$2$1/g;

Update: If you must exchange them one by one to percolate the first character over to the last, I won't help. I'd just say: s/(.)(.*)/$2$1/; That's fairly close to my original.

Update2: What you say doesn't describe what you have. Nevermind, I'll let the psychics figure it out.
