[Rails] how to make the whenever gem to run a cron job

If you are using cron then you do not need to use whenever. Simple
run the rake task from cron.

Whenever just helps to use cron with simple ruby syntax.
To make it run cronjobs. You need to:
1. Exec in your project folder:
wheneverize .
This will create config/schedule.rb file.

2. There type some action needed to be done with cron:
every 3.hours do
rake "my:rake:task"
end

3. Save it and execute that
whenever --update-crontab
This will update crontab file.
You can ensure that crontab is written by
crontab -l

4. And final point restart cron
sudo services cron restart

Enjoy =)

If I had looked up whenever before replying then my post might have
been more helpful :(

sudo services cron restart"

restart the cron,but did not work,do you have any fixes for that
