Overview

Public: Simple system call. Use it when you need to just execute something, eventually silently and you don’t care about the result. Uses ‘system` under the hood. Feel free to inherit from this class, example:

class GitCommit < Perfume::Shell::SystemCall
  args :message

  def cmd
    'git commit -m #{@message.inspect}'
  end
end
