A shell script for Tot

tot.sh

#!/bin/sh

basename=`basename $0`

if [ -z "$*" ]; then
	echo "usage: ${basename} <dot> [ -o | -r | <file> | - ]"

	echo "  -r      read contents of dot"
	echo "  -c      clear contents of dot"
	echo "  <file>  append contents of regular file to dot"
	echo "  -       append standard input to dot"
	echo ""
	echo "examples:"
	echo "  $ cal -h | tot 1 -    # put a calendar in first dot"
	echo "  $ tot 2 MyApp.crash   # put a crash report in second dot"
	echo ""

	echo "error: no dot action specified"

	elif [ "$2" = "-c" ]; then

	else
		# append file or stdin to dot

			fi

		text=`cat $FILE | python -c 'import urllib; import sys; print urllib.quote(sys.stdin.read())'`
		osascript -e "tell application \"Tot\" to open location \"tot://${dot}/append?text=${text}\""
	fi
fi

Nit - usage & examples - tot should be tot.sh in this case -> ${basename}.

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?
