title: How do you comment out lines in AWS CLI config and credentials files?
body: <p>For AWS CLI configuration and credentials files how do you comment out lines in these files - I checked the documentation here <a href="http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html#cli-config-files" rel="noreferrer">http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html#cli-config-files</a> but found nothing.</p>
  
  <p>e.g.</p>
  
  <p>~/.aws/credentials</p>
  
  <pre><code>[default]
  aws_access_key_id = XXXXXXXXX
  aws_secret_access_key = YYYYYYYY
  
  [qa]
  aws_access_key_id = AAAAAAAAA
  aws_secret_access_key = BBBBBB
  </code></pre>
  
  <p>~/.aws/config</p>
  
  <pre><code>[default]
  region = us-east-1
  
  [profile qa]
  region = us-west-2
  
  [profile staging]
  region = us-east-2
  </code></pre>
