How to cancel a pull request in GitHub?

 
Step 1: Prepare your environment
 

• Ensure you have a GitHub account and are logged in.
• Navigate to the repository containing the pull request you want to cancel.

 
Step 2: Access the Pull requests tab
 

• In your repository, click on the Pull requests tab at the top of the page.

 
Step 3: Locate the pull request you want to cancel (close)
 

• Scroll through the list of open pull requests or use the search/filter box to quickly find it.
• Click on the title of the pull request to open its details page.

 
Step 4: Close the pull request via the web interface
 

• On the pull request details page, scroll down to the bottom.
• Click the Close pull request button located next to the comment box.
• Optionally, enter a comment explaining why you’re closing it, then click Close pull request again to confirm.

 
Step 5: Cancel a pull request using GitHub CLI
 

• If you prefer the command line, install GitHub CLI (gh) first:

# macOS (Homebrew)
brew install gh

# Windows (Scoop)
scoop install gh

# Debian/Ubuntu
sudo apt update
sudo apt install gh

• Authenticate to GitHub from the CLI:

gh auth login

• List open pull requests for your repository:

gh pr list --repo owner/repo

• Close the pull request by its number or URL:

# By pull request number
gh pr close 123

# Or by full URL
gh pr close https://github.com/owner/repo/pull/123

 
Step 6: Verify that the pull request is closed
 

• Return to the Pull requests tab in your repository.
• Switch to the Closed filter to confirm that your pull request appears there.
