Wrapper for googlecl calendar

Recently I was searching for tool to keep my TODO list synchronized with my laptop and my mobile phone. One simple and effective solution is to use googlecl tool to manage the calendar entries. I've written a simple wrapper to make it really easy to work with googlecl and to use it as a simple TODO list for console.


The basic thought was to create a simple tool to view, add and remove tasks (all day events in google calendar). First you will need to install the googlecl package. You can find it in standard repositories or HERE.
When you will run your first command, you will be asked to allow permissions to access the calendar. Login to your Google account and allow access for googlecl tools.
Afterward you can use my wrapper. The usage is following:

list all               List all events in calendar.
list today          List events for today.
list                    List events for upcoming week.
add today <string>      Add event for today.
add <NR> <string>       Add event for <NR> days.
del <string>            Delete event from calendar.

Examples:
gcal list -this will list events for upcoming week
gcal add 4 this is my memo -add event for 4 days
To delete an event use first letters from event to find it:
gcal del this
For calendar MyCalendar
Are you SURE you want to delete event "this is my memo"? (y/N): y
-if there are several matches the question will repeat

Beware of using memos like: my memo for 4 days, my memo for tomorrow, as this can be wrong interpreted and added to the calendar. Also if you need to use . (dot) or some other signs it might not work. You need to try, it seems like sometimes it works and sometimes don't.
NOTE: set in the script (del section) your calendar name.

Here's the script:

#!/bin/bash

TODAY=`date +%Y-%m-%d`
NEXTWEEK=`date -d 'next week' +%Y-%m-%d`
MONTH=`date +%b`
