Introduction

Working with Git can sometimes lead to frustrating issues, especially when dealing with environment variables. One common problem is trying to use environment variables in Git commands like git remote add, but finding that they aren't recognized or evaluated correctly. This can hinder your workflow, especially if you're trying to simplify your command line operations using variables for URIs or other configurations.

In this guide, we'll address the problem of using environment variables in Git commands and provide a clear solution to get you back on track.

The Problem: Environment Variables Not Evaluating

When you attempt to run a command like:

However, not everyone finds success with this approach. So, what’s the solution?

The Solution: Use Uppercase Environment Variables

After some testing, a potential solution surfaced: make sure your environment variable is defined in all uppercase. Specifically, when you change original_uri to ORIGINAL_URI in your commands, it suddenly starts working.

Step-by-Step Guide to Fix the Issue

Define Your Environment Variable in Uppercase:
Change the variable name from original_uri to ORIGINAL_URI when you set it. For example:

Why Does This Work?

The reason behind this fix lies in how shell environments sometimes parse and evaluate variables. Uppercase variables are a convention used in many programming contexts, including Bash and Git, which may help avoid conflicts or misinterpretations.

Conclusion

By using uppercase environment variable names, you can avoid the problem of Git not evaluating your variables correctly in commands like git remote add. This simple change has been an effective workaround for many users facing similar issues.
