GitHub CLI: gives wings to terminal

GitHub CLI: gives wings to terminal

When working with git, you’re obviously aware that you need to switch to the web browser to perform various actions on the GitHub repo - Pull Request, Issues, Review... The GitHub CLI tool gives wings to the cmd-line, so you can execute many of these actions without leaving the cmd-line.

Setup

To get started, visit the installation page and find instructions on how to install GitHub CLI for your preferred OS. The easy-peasy way for Windows users is to use scoop package manager.

Below are snapshots of install instructions for each supported platform:

  • Windows:

      scoop bucket add github-gh https://github.com/cli/scoop-gh.git
      scoop install gh
    
  • macOS:

      brew install github
    
  • Debian/Ubuntu Linux:

      sudo apt install git && sudo dpkg -i gh_*_linux_amd64.deb
    

Authenticate GitHub CLI

Authenticate CLI to access your GitHub account.

gh auth login

Select Login with a Web browser

$ gh auth login
? What account do you want to log into? GitHub.com
? What is your preferred protocol for Git operations? HTTPS
? Authenticate Git with your GitHub credentials? Yes
? How would you like to authenticate GitHub CLI? Login with a web browser

! First copy your one-time code: 1DD9-7BD3
Press Enter to open github.com in your browser... 
✓ Authentication complete.
- gh config set -h github.com git_protocol https
✓ Configured git protocol
✓ Logged in as pvishnuprasaath


GitHub CLI Command Struct

gh command is structured like a tree for grabbing easily. There are basically two levels of commands. The first level consists of the below commands:

  • auth

  • browse

  • issue

  • pr

  • release

  • repo

  • codespace

  • gist

Each command has a second level of command where you specify the operation to perform — such as gh pr create or gh repo view.

Let's dive deep into the most commonly used commands.


GitHub Repo Command

Cloning a repo with the gh command is easier than using the git command. You no longer need to type or copy-paste the long Git URL to clone

gh repo clone OWNER/REPO
gh repo clone mui/material-ui

You can also fork existing repositories to your account easily from the command line.

gh repo fork cli/cli

To view the description and README of a project hosted on GitHub use the gh repo view command.

gh repo view facebook/react

Let's create a new GitHub repository from the command line. First, we need to create a new project.

$ npx create-next-app sample-app
$ cd sample-app

To create a repo from the command line, just run the following:

$ gh repo create --public
✓ Created repository pvishnuprasaath/sample-app on GitHub
✓ Added remote https://github.com/pvishnuprasaath/sample-app.git

# Push your project code to your new remote repository
$ git push -u origin main

Pull Request Command

If you know classic git flow, creating PR is quite an effort. GitHub CLI makes it easy to create PR directly from your terminal. After a git commit, you can execute gh pr create. It will prompt a couple of inputs. Post that, the PR link is displayed in the terminal.

Here’s the full output:

$ gh pr create
Creating pull request for feature-1 into master in pvishnuprasaath/sample-app
? Title Added new feature
? Body Implemented and testted new feature for ABC
? What is  next? Submit

remote:

* [new branch]      HEAD -> feature-1
Branch 'feature-1' set up to track
remote branch 'feature-1' from 'origin'.
https://github.com/pvishnuprasaath/sample-app/pull/3

A short version:

gh pr create --title "PR title" --body "PR body"

To view all the pull requests in the current repo, run gh pr list

$ gh pr list
Showing 1 of 1 pull request in pvishnuprasaath/sample-app
#3  Added new feature  feature-1

Use the command gh pr checkout <number> to checkout a PR. This command will pull the remote feature branch and switch to it. gh pr diff will show the delta for the current PR.

Let’s take a look at the gh pr merge command. As you’re probably aware, GitHub checks for vulnerabilities in your code and provides solutions via bump pull requests. Here’s an example:

Merging multiple PRs one by one is a tiring process. gh pr merge makes it easy to merge a particular PR directly from the terminal.

$ gh pr merge 4

Additional gh pr commands

By now, there isn't a way to revert PR from the GitHub CLI yet :(


Issue Command

Issues are used to keep track of bugs, tasks and feature requests associated with a GitHub project repo. The command gh issue create is used to create a new issue via the terminal:

$ gh issue create
Creating issue in pvishnuprasaath/sample-app
? Title Fix Docker skill link

? Title Fix Docker skill link
? Body <Received>
? What's next? Submit
https://github.com/pvishnuprasaath/sample-app/issues/6

gh issue list command lists all issues in the current repo.

The rest of gh issue commands are quite similar to gh pr commands. Below is a quick summary:


GitHub CLI Cheat Sheet

Creating, deleting and configuring repo

gh repo create

gh repo create <name_of_repo> --public

gh repo create my-project --private --source=. --remote=upstream

gh repo edit --visibility <visibility-string>

gh repo sync

gh repo create --disable-issues=true --public

gh repo list

gh repo delete <name_of_repo>

gh repo clone <name_of_repo>

gh repo fork <name_of_repo>

To easily save a piece of code online use Gist:

Creating a gist

touch index.js // after create content for it

gh gist create index.js --public

gh gist create -

gh gist edit <gist_id> 

gh gist list --public 

gh gist list --secret

Handling issues

gh issue create

gh issue list

gh issue status

git issue close <#number_issue>

gh list -A "<name_issue>"

Handling Pull requests

gh pr create 

gh pr checkout <name>

gh pr diff <#number_of_pr>

gh review -c -b "nice work"

gh pr close <#number_of_pr> -d

gh pr reopen <#number_of_pr>

gh pr status

gh for sure saves up time in devflow. Gives additional hands to your terminal for managing the repository. Refer to the official docs for new features and detailed info on using the existing commands.
