Please select a continent or ocean.  1) Africa  2) Americas  3) Antarctica  4) Arctic Ocean  5) Asia  6) Atlantic Ocean  7) Australia  8) Europe  9) Indian Ocean 10) Pacific Ocean 11) none - I want to specify the time zone using the Posix TZ format pi@raspberrypi ~ $ tzconfig WARNING: the tzconfig command is deprecated, please use:  dpkg-reconfigure tzdata pi@raspberrypi ~ $ dpkg-reconfigure tzdata /usr/sbin/dpkg-reconfigure must be run as root pi@raspberrypi ~ $ sudo dpkg-reconfigure tzdata                                                                                       Current default time zone: 'America/Toronto' Local time is now:      Tue Oct  6 10:55:18 EDT 2015. Universal Time is now:  Tue Oct  6 14:55:18 UTC 2015. pi@raspberrypi ~ $ date Tue Oct  6 10:55:28 EDT 2015

2. Access the Raspberry Pi Desktop

XRDP service will allow you to use remote desktop to access Raspberry Pi GUI through VNC service.

3. List System Information

pi@raspberrypi ~ $ uname -a Linux raspberrypi 3.18.7-v7+ #755 SMP PREEMPT Thu Feb 12 17:20:48 GMT 2015 armv7l GNU/Linux

4. Add Cron Job

Add a cron job to halt Raspberry Pi at 23:00 everyday.

pi@raspberrypi ~ $ crontab -e   GNU nano 2.2.6           File: /tmp/crontab.obWc51/crontab                           # Edit this file to introduce tasks to be run by cron. # # Each task to run has to be defined through a single line # indicating with different fields when the task will be run # and what command to run for the task # # To define the time you can provide concrete values for # minute (m), hour (h), day of month (dom), month (mon), # and day of week (dow) or use '*' in these fields (for 'any').# # Notice that tasks will be started based on the cron's system # daemon's notion of time and timezones. # # Output of the crontab jobs (including errors) is sent through # email to the user the crontab file belongs to (unless redirected). # # For example, you can run a backup of all your user accounts # at 5 a.m every week with: # 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/ # # For more information see the manual pages of crontab(5) and cron(8) # # m h  dom mon dow   command 0 23 * * * sudo halt                                    [ Wrote 24 lines ] crontab: installing new crontab
