Tell Ruby Program to Wait some amount of time

Question

How do you tell a Ruby program to wait an arbitrary amount of time before moving on to the next line of code?

Answer 1

Like this:

sleep(num_secs) 

The num_secs value can be an integer or float.

Also, if you're writing this within a Rails app, or have included the ActiveSupport library in your project, you can construct longer intervals using the following convenience syntax:

sleep(4.minutes) # or, even longer... sleep(2.hours); sleep(3.days) # etc., etc. # or shorter sleep(0.5) # half a second
