Where did my original .bash_profile go? 

It's nice that we make a backup but…
 * what if a back-up already exists?
 * what if this is the 2nd, 3rd or 4th time I'm executing the script?

We backup to .bash_profile.bak or .bash_plofile.bak.{count} if .bash_plofile.bak already exists.
iow
.bash_plofile.bak if not exist
.bash_plofile.bak.1 if exists
.bash_plofile.bak.2 if 2 exists
.bash_plofile.bak.3 if 3 exists etc…

Newest backup with the highest number.
