title: How to set cURL default --insecure option?
body: <p>I have to execute a command which executes a few other set of commands automatically. One of those commands is:</p>
  
  <p><code>curl -k https://github.com/google/protobuf/releases/download/v3.5.1/protoc-3.5.1-linux-x86_64.zip</code></p>
  
  <p>But I want this command to run with an <code>--insecure</code> flag so that the verification of curl's certificate doesn't take place as I'm behind a corporate proxy.</p>
  
  <p>I understand that I need to edit the <code>.curlrc</code> file to add the <code>--insecure</code> option.</p>
  
  <p>I checked my $HOME directory, and such a file doesn't exist. Should a create a new .curlrc file? What should be its content to start with? How does a sample .curlrc file look like? What all are its contents?</p>
  
  <p>I found this link: <a href="https://gist.github.com/v1m/f1d4751883f19c916515" rel="nofollow noreferrer">Sample .curlrc file</a>. However, this doesn't explain things clearly.</p>
