title: How to override the env variables and use the AWS credential file instead in AWS CLI?
body: <p>When using AWS CLI, is there a way I can specify it to use the credential file instead of the values stored in the env variables?</p>
  
  <p><code>$ aws ec2 describe-instances --profile saml</code></p>
  
  <p><code>saml</code> is a profile name inside the credentials file stored in ~/.aws/credentials. I want the AWS CLI to use this credential file by default and not use the ones stored in the env variable. How can I do this?</p>
