How to Create a Custom Command for Cloning GitHub Repositories in Ubuntu

If you're a developer frequently cloning repositories, typing the full git clone command can feel repetitive. Wouldn't it be nice to simplify the process to something like:

clone username/repository

This blog walks you through creating a custom clone command on Ubuntu that lets you clone GitHub repositories with ease.

Step 1: Understanding the Problem

By default, there’s no command named clone in your shell. Attempting to use it results in an error like this:

zsh: command not found: clone

This is because the clone command isn't natively available. However, we can create a custom command to achieve this functionality.

Step 2: The Solution

We’ll define a shell function called clone to:

1. Accept the repository identifier in the format username/repository.
2. Automatically construct the GitHub URL.
3. Execute the git clone command behind the scenes.

Step 3: Creating the Custom Command

To set this up:

1. Open the Shell Configuration File

   Since you're using zsh, edit the .zshrc file:
   

   nano ~/.zshrc
   

2. Add the Custom Function

   Append the following code to the file:
   

   clone() {
     if [ $# -eq 1 ]; then
       git clone "https://github.com/$1.git"
     else
       echo "Usage: clone <username/repository>"
     fi
   }
   

3. Apply the Changes

   Reload your shell to activate the new function:
   

   source ~/.zshrc
   

What It Does:

- `$#` checks the number of arguments passed.
- Constructs the GitHub URL dynamically.
- Executes the `git clone` command or displays usage 
  instructions if no arguments are provided.

Step 4: Test Your New Command

Now, you can clone repositories with a single command:

clone Suraj-kumar00/DevOps

The output should look like this:

Cloning into 'DevOps'...
remote: Enumerating objects: 42, done.
remote: Counting objects: 100% (42/42), done.
remote: Compressing objects: 100% (30/30), done.
remote: Total 42 (delta 10), reused 42 (delta 10), pack-reused 0
Receiving objects: 100% (42/42), 6.92 KiB | 6.92 MiB/s, done.
Resolving deltas: 100% (10/10), done.

Benefits of This Custom Command

• Saves Time: No need to type long git clone URLs.
• Ease of Use: Simple syntax—just provide username/repository.
• Customizable: You can modify the function to support other Git hosting platforms like GitLab or Bitbucket.

Optional Enhancements

Want to extend the functionality further? Here are some tips:

1. Support for Non-GitHub Platforms: Add logic to detect and handle URLs for GitLab or Bitbucket repositories.
2. Error Handling: Include checks for valid GitHub repository URLs or network connectivity.

3. Alias Instead of Function:
   If you want a simpler setup, you can define an alias instead:
   

   alias clone='git clone https://github.com'
   

THE END

With this small tweak, you’ve created a custom command that simplifies your workflow. Whether you're cloning repositories daily or just looking for a more efficient setup, this custom clone command is a simple yet powerful productivity boost.

Give it a try and see how much time you save! 🚀
