Another thing to consider is the sort order. In zsh, you can get a proper numeric sort fairly easily, so 2.10 is greater than 2.9.

Here is a zsh one-liner.

echo "${(@n)RUBIES}"

Or to print each Ruby in order:

printf "%s\n" "${(@n)RUBIES:t}"

done
unset dir
function chruby_rubies()
{
if [ -n "$ZSH_VERSION" ]; then
setopt local_options nodotglob nullglob
else
trap "$(shopt -p dotglob nullglob)" RETURN
shopt -u dotglob
shopt -s nullglob
fi

local dir
for dir in "$@"; do
[[ -d "$dir" ]] && RUBIES+=("$dir"/*)
done
}
chruby_rubies "$PREFIX/opt/rubies" "$HOME/.rubies"
unset -f chruby_rubies

function chruby_reset()
