Hey there! Let's figure out why your curl command works smoothly in Windows CMD but acts up in Git Bash. Here are some targeted fixes to try out:

1. Fix Terminal Interaction with winpty #

Git Bash sometimes struggles with handling interactive prompts (like password requests) for certain commands. Try wrapping your curl command with winpty to force proper terminal interaction:

winpty curl -i -u myuser https://api.github.com/users/myuser

This often resolves cases where the password prompt doesn't appear or the command hangs unexpectedly.

2. Use a GitHub Personal Access Token (PAT) Instead of Password #

GitHub has deprecated password-based authentication for many API operations, and using a PAT is not only more reliable but also more secure. Here's how to do it:

• Generate a PAT from your GitHub account settings (make sure it has the user scope enabled)
• Use the token directly in your curl command, or store it as an environment variable for reuse:

  # Option 1: Use the token directly
  curl -i -u myuser:your_pat_here https://api.github.com/users/myuser
  
  # Option 2: Store as an environment variable
  export GITHUB_PAT=your_pat_here
  curl -i -u myuser:$GITHUB_PAT https://api.github.com/users/myuser
  

This bypasses any password prompt issues entirely and is a better long-term approach.

3. Reset Git Credential Cache #

Git might be caching outdated or invalid authentication credentials that interfere with the curl command. Clear the cache with:

git credential-cache exit

If you're using Windows Credential Manager instead, head to Control Panel > User Accounts > Credential Manager > Windows Credentials and remove any entries linked to GitHub.

4. Verify Git Bash's Curl Configuration #

Git ships with its own version of curl, which might have different settings than the system-wide curl used in CMD. Check the version and try using the system curl instead:

# Check curl version in Git Bash
curl --version

# Try using the system-wide curl in Git Bash (replace path if needed)
C:\Windows\System32\curl.exe -i -u myuser https://api.github.com/users/myuser

A version mismatch or conflicting configurations could be the root cause here.

5. Check for Proxy or Environment Variable Conflicts #

Git Bash might inherit proxy settings or environment variables that CMD doesn't, which can block authentication. Compare the environment variables in both terminals:

• In Git Bash: env | grep -E "(HTTP_PROXY|HTTPS_PROXY|USER)"
• In CMD: set | findstr /i "HTTP_PROXY HTTPS_PROXY USERNAME"
  If you spot unexpected proxy settings, unset them in Git Bash with:

unset HTTP_PROXY
unset HTTPS_PROXY

Then re-run your curl command to test.
