Subject: [PATCH] What if .bash_profile doesn't exist?

We get an error from cp
We still respond that we made a backup
Instead if .bas_profile exists and cp is a success then prompt informing the user that we made a backup
or inform them that no .bash_profile was found so no need to make a back up at this point.
