hub Command Examples
1. Clone a repository using its slug (owners can omit the username):
# hub clone [username]/[repo_name]
2. Create a fork of the current repository (cloned from another user) under your GitHub profile:
# hub fork
3. Push the current local branch to GitHub and create a PR for it in the original repository:
# hub push [remote_name] && hub pull-request
4. Create a PR of the current (already pushed) branch, reusing the message from the first commit:
# hub pull-request --no-edit
5. Create a new branch with the contents of a pull request and switch to it:
# hub pr checkout [pr_number]
6. Upload the current (local-only) repository to your GitHub account:
# hub create
7. Fetch Git objects from upstream and update local branches:
# hub sync
Summary
Overall, “hub” is a valuable tool for developers and GitHub users who want to streamline their Git and GitHub workflows. Its integration with Git, simplified commands, and seamless GitHub integration make it an essential component of the development toolkit for GitHub-based projects.
