The Drupal One-Click application comes with Drush, a command line tool for administering Drupal., pre-installed. It allows you to upgrade Drupal easily.
First change into the directory containing Drupal:
cd /var/www/html/drupal/
To check for an available update run:
drush pm-update -n
And to update to the new release, run:
drush pm-update drupal-7.34
For more info on what you can do with Drush, check out:
Drush is a very useful tool which helps you perform various admin tasks using just one or two commands in the terminal, replacing the many clicks and page refreshes needed in the UI. This tutorial will go through some of the basic Drush commands and will work with a standard Drupal installation to illustrate them.

Amazing, thank you :) I had only used Drush for basic user based commands and managing views. So this is great. Thanks! :)
Just to update. Some might get this error.
Command pm-update needs a higher bootstrap level to run - you will need to invoke drush from a more functional Drupal environment to run this command. [error]
The drush command 'pm-update' could not be executed. [error]
Drush was not able to start (bootstrap) the Drupal database. [error]

I got this error too - I got around it by changing the password in
/root/.my.cnf, (which was originally the root DB user password) to the drupal user password. That password can be found at the end of the file in/var/www/html/drupal/sites/default/settings.phpwhere the database connection for the site is set up.Inspired by answers here: https://www.digitalocean.com/community/questions/error-using-drush-with-new-drupal-installation-of-drupal-8
