I am always needing to have quick access to a calendar to set deadlines and plan out various tasks. Using Ubuntu’s Terminal, you can quickly pull up a calendar of any month or year (past, present, or future).
1. Open a Terminal window.
2. To view a single month, execute the following Terminal command (make sure to input both the desired month and year}:
cal december 2008
To view an entire year, execute the following Terminal command (make sure to input the desired year):
cal 2009
To view last month, this month and next month, execute the following Terminal command:
cal -3
