:+1: nice work. The point of this homework was to introduce the node.js runtime and asynchronous IO through a series of common and simple filesystem CLI Utilities. Here's a checklist of things that I'm looking for in this project. You should review the checklist, and make any changes to your project, if necessary.

• Airbnb has a good summary of appropriate JavaScript coding conventions, you should take a quick look here.
• Familiarity with core APIs is critical to understanding the capabilities of the node.js runtime. No packages should have been necessary to complete this assignment.
• Modularize your code as much as possible, and avoid globals. Separating functionality into separate modules will make your code more extensible and supportable.
• Handle errors properly with process.on('uncaughtException', ...) and process.on('unhandledRejection', ...) handlers and utilizing trycatch for long-stack-trace support.
• You should always take extra precautions like this when interacting with the filesystem to avoid catastrophic mistakes like removing /.
• Sync APIs should never be used in production code except during the brief startup phase of a server's lifecycle. Use the safeguards package to protect against this.
• Your CLI files should always be executable. Always remember to add the appropriate permissions and a shebang.

In general, you should strive to create small composable modules that do one thing well, consistent with The Unix Way. Keep this in mind as you dive further into more complex architectures and applications.
