What does the fail keyword do in Ruby?

Question

I am learning Ruby and encountered the fail keyword. What does it mean?

if password.length < 8
   fail \"Password too short\"
end
unless  use

Rubocop says about usage of both words;

'Use fail instead of raise to signal exceptions.'

'Use raise instead of fail to rethrow exceptions.'

Here is an example.

def sample
  fail 'something wrong' unless success?
rescue => e
  logger.error e
  raise
end
