The GitHub CLI (
gh) does not have commands like
gh status or
gh diff to view local changes. To manage local Git lot changes, you must use standard Git commands such as
git status and
git diff within your terminal. The
gh tool integrates with these workflows primarily for repository management, pull request creation, and issue tracking, rather than replacing core Git inspection utilities.
Understanding the Limitation of gh
Many developers assume that because
gh is a powerful command-line interface for GitHub, it should replace all Git operations. However, this is a common misconception. The
gh CLI is designed to interact with the GitHub API, handling tasks that require authentication and network connectivity. It does not parse local
.git directories directly. Therefore, commands that inspect the working tree, staging area, or commit history locally are outside its scope. You will encounter errors if you attempt to run non-existent subcommands. For example, trying to execute
gh status will result in an error stating that the command is not found. Similarly,
gh branch list is invalid; branching is managed via
git branch.
This distinction is crucial for maintaining an efficient workflow. By understanding what
gh can and cannot do, you avoid frustration and confusion. Instead of looking for a magic
gh command to show unstaged files, you should rely on the robust set of tools provided by Git itself. This approach ensures that your local development environment remains consistent and predictable, regardless of whether you are using
gh for remote interactions.
Viewing Local Changes with Standard Git Commands
To see what has changed in your local repository, you must use Git's native commands. These commands are fast, reliable, and work offline. The primary command for viewing changes is
git status. When you run this in your terminal, it provides a summary of which files have been modified, which are staged for commit, and which are untracked.
git status
The output will typically look like this:
- Changes not staged for commit: Files you have edited but not added to the index.
- Changes to be committed: Files you have added using
git add.
- Untracked files: New files that Git is not yet monitoring.
If you need to see the actual content differences, use
git diff. This command shows the line-by-line changes between your working directory and the last commit (or the staging area). For example,
git diff HEAD shows all changes since the last commit. If you want to see only the changes you have staged, use
git diff --cached. These commands are essential for reviewing your work before creating a commit or a pull request.
For a more visual representation of file differences, some users prefer graphical interfaces or extensions. However, for command-line efficiency,
git diff remains the gold standard. It allows you to quickly scan changes without leaving the terminal. This method is far superior to inventing non-existent CLI shortcuts that do not exist in any version of the GitHub CLI.
Checking Identical Files
Sometimes you may wonder if two files are identical before deciding to commit or discard changes. While Git tracks changes, it does not provide a direct "compare file A to file B" command in the same way operating system utilities do. For checking identical files, you might use system-level tools. As discussed in our guide on
Safe Way to Check Identical Files: A Comparison of 'fc' and 'cmp', tools like
fc (on Windows) or
cmp (on Unix-like systems) can verify file identity. This is useful when you suspect a file was overwritten incorrectly or when debugging sync issues.
Using gh for Remote Workflow Integration
While
gh does not handle local diffs, it excels at bridging the gap between your local changes and GitHub. Once you have reviewed your changes with
git status and
git diff, you can use
gh to create a pull request, view issues, or manage branches on the remote server.
The most common workflow involves committing your changes locally first. After running
git commit -m "Your message", you can push the branch to GitHub using
git push. Then, you can use
gh pr create to open a pull request from your current branch. This command automatically detects the upstream branch and opens a browser window or prepares the PR body based on your configuration.
gh pr create --title "Feature Update" --body "Updated logic for X"
You can also use
gh pr list to see open pull requests across repositories you have access to. This is helpful for code review management. Additionally,
gh issue list allows you to track bugs and feature requests associated with your repository. These commands leverage the GitHub API to provide context that is not available locally.
Another powerful feature is
gh repo clone, which simplifies cloning repositories with the correct authentication method. Instead of manually configuring SSH keys or HTTPS credentials,
gh repo clone owner/repo handles the setup seamlessly. This reduces friction when starting new projects or switching contexts.
Common Mistakes and Troubleshooting
A frequent error is assuming that
gh replaces
git. Always remember that
git manages your local state, while
gh manages your GitHub state. If you try to use
gh to resolve merge conflicts, you will find no support for that. Merge conflicts must be resolved manually in your text editor, followed by
git add and
git commit.
Another mistake is neglecting to authenticate
gh. Before using most
gh commands, you must run
gh auth login. This step ensures that your CLI has the necessary permissions to read and write data to GitHub. Without authentication, commands like
gh pr create will fail with permission denied errors.
For issues related to authentication and security, refer to our article on
Do Authenticators Work on GitHub Sites?. Understanding how multi-factor authentication interacts with CLI tools can prevent access issues during critical development phases.
Best Practices for Efficient Development
Integrate
git and
gh into a cohesive workflow. Use
git status frequently to monitor your progress. Use
git diff to verify changes before committing. Once committed, use
gh to handle remote interactions. This separation of concerns keeps your workflow clean and understandable.
Avoid relying on aliases or scripts that mimic non-existent
gh commands. Stick to the official documentation for both tools. The GitHub CLI documentation is comprehensive and regularly updated. Similarly, Git’s manual pages are invaluable for mastering local operations.
By combining the strengths of both tools, you achieve a seamless development experience. You get the power of Git for local control and the convenience of GitHub CLI for remote collaboration. This hybrid approach is the industry standard for modern software development teams.
Frequently Asked Questions
Can I use gh to see unstaged changes?
No, the GitHub CLI cannot view unstaged local changes. You must use
git diff for this purpose.
gh only interacts with data stored on GitHub, not your local working directory.
What is the correct command to list local branches?
Use
git branch to list local branches. There is no
gh branch list command. To list remote branches, you can use
git branch -r or
gh repo view --json defaultBranchRef for specific remote details.
How do I create a pull request using gh?
After pushing your branch, run
gh pr create. This command will prompt you for a title and body, then open a browser to finalize the pull request. Ensure your branch is pushed to the remote repository first.
Why does gh auth login ask for a token?
GitHub requires authentication for most CLI actions to ensure security. You can generate a personal access token in your GitHub settings under Developer Settings. This token grants
gh permission to act on your behalf.
Is gh useful for cloning repositories?
Yes,
gh repo clone is highly recommended. It automatically configures authentication, saving you from manually setting up SSH keys or managing HTTPS credentials. It streamlines the initial setup process significantly.
