This is the second post regarding basic configuration of Raspberry Pi 2.

1. Timezone change

By default, Raspberry Pi 2 will use UTC time. Command tzselect will give you continent and country selection to pick.

Tue Oct  6 13:48:38 UTC 2015
[email protected] ~ $ tzselect
Please identify a location so that time zone rules can be set correctly.
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

[email protected] ~ $ tzconfig
WARNING: the tzconfig command is deprecated, please use:
 dpkg-reconfigure tzdata
[email protected] ~ $ dpkg-reconfigure tzdata
/usr/sbin/dpkg-reconfigure must be run as root
[email protected] ~ $ 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.

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

[email protected] ~ $ 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.

[email protected] ~ $ 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
