-You can silence any stream while a block runs with `silence_stream`:
-
-```ruby
-silence_stream(STDOUT) do
- # STDOUT is silent here
-end
-```
-
-The `quietly` method addresses the common use case where you want to silence STDOUT and STDERR, even in subprocesses:
-
-```ruby
-quietly { system 'bundle install' }
-```
-
-For example, the railties test suite uses that one in a few places to prevent command messages from being echoed intermixed with the progress status.
-
Silencing exceptions is also possible with `suppress`. This method receives an arbitrary number of exception classes. If an exception is raised during the execution of the block and is `kind_of?` any of the arguments, `suppress` captures it and returns silently. Otherwise the exception is reraised:
```ruby
-# If the user is locked the increment is lost, no big deal.
+# If the user is locked, the increment is lost, no big deal.
suppress(ActiveRecord::StaleObjectError) do
current_user.increment! :visits
end
