Sometimes running a command in a pry session
can produce a bunch of verbose output that you aren't interested in seeing.
Here is a contrived line of code whose output will take over the entire screen:
(1..200).map { |i| i*i }
#=> [1,
4,
9,
16,
...You can silence all of this output by tacking on a single character -- ;.
(1..200).map { |i| i*i };
