Those of us with 'set -o noclobber' get this on every other vscreen invocation:

-bash: /.../oh-my-vagrant/vagrant/.ssh/ansible1.config: cannot overwrite existing file

(fixed by !!, because of the '|| rm "$f"). Could I suggest changing > (greater-than) to >| (greater-than pipe) in the three instances of vagrant ssh-config "$1" > "$f" ?
