        echo "Processing alias $aname as $command"
        if test -f ~/.config/fish/functions/$aname.fish
            echo Function $aname is already defined. Skipping ...
        else
            alias $aname $command
            funcsave $aname
        end
    end
end

This gist only works for aliases with the following format: alias name="command"
