 Sometimes you write a script that does something but you want for it to run periodically, say a backup task. You can always write an *ad hoc* solution that runs in the background and comes online periodically. However, most UNIX systems come with the cron daemon which can run task with a frequency up to a minute based on simple rules.
 
 On most UNIX systems the cron daemon, `crond` will be running by default but you can always check using `ps aux | grep crond`.

 It has become more and more common for programmers to use remote servers in their everyday work. If you need to use remote servers in order to deploy backend software or you need a server with higher computational capabilities, you will end up using a Secure Shell (SSH). As with most tools covered, SSH is highly configurable so it is worth learning about it.
