title: custom npm config (.npmrc) path for npm command
body: <p>Is there a way to specify the custom .npmrc file path with npm command?</p>
  
  <p>The context for the question: In a node js build and release pipeline (azure DevOps and Jenkins pipeline), I don't want to keep the .npmrc config which contains private registry path and _auth details in the git repository, Hence I want to generate it on the go with a different name, so that I can specify the file path along with npm command and use it and destroy it. </p>
