A shell script for Tot

		osascript -e "tell application \"Tot\" to open location \"tot://${dot}/append?text=${text}\""
	fi
fi

Curious as to why using osascript -e "tell application \"Tot\" to open location \"tot://${dot}/append?text=${text}\"" instead of open "tot://${dot}/append?text=${text}"

I have an issue where the flags don't seem to be recognized. When I try commands like "tot -o 1" or "tot -r 3" I get the "not a regular file" error. Any ideas for how to fix this?

Is it possible to determine which dot is the currently open one?
