This script clones a GitHub repository named "repository" into a local "project" directory, only if the "master" branch doesn't already exist locally.

Run example

npm run import -- "project repository"

project repository

mkdir -p project ; \
if git --work-tree=./project branch | grep 'master'; \
then echo \"Already checked out project\"; \
else git clone https://{username}@github.com/username/repository ./project ; \
fi ; ls -la project ; \
pwd

#!/bin/bash

# Create a project directory if it does not exist
mkdir -p project || echo "Error creating project directory"

# Change the current working directory to the project directory
cd project

# Checkout the master branch
if git branch | grep -q'master'; then
  echo "Already checked out project"
else
  # Clone the repository if it does not exist
  git clone https://github.com/username/repository.git || echo "Error cloning repository"
fi

# Print the directory contents
ls -la

# Print the current working directory
pwd

This code snippet checks out a Git repository named "repository" from GitHub into a local directory named "project".

Here's a breakdown:

1. Directory Creation:

   • mkdir -p project: Creates a directory named "project" if it doesn't exist. The -p flag ensures that any necessary parent directories are also created.

2. Branch Check:

   • if git --work-tree=./project branch | grep 'master'; then:
     • git --work-tree=./project branch: Lists branches within the "project" directory.
     • grep 'master': Checks if the "master" branch exists in the list.
     • then echo "Already checked out project";: If the "master" branch exists, it prints a message indicating that the project is already checked out.

3. Cloning Repository:

   • else git clone https://{username}@github.com/username/repository ./project; fi:
     • If the "master" branch doesn't exist, it clones the repository from the specified URL into the "project" directory.

4. Listing Files:

   • ls -la project: Lists all files and directories within the "project" directory with detailed information.

5. Current Directory:

   • pwd: Prints the current working directory.

In essence, this script checks if a local "project" directory exists and if it contains the "master" branch. If not, it clones the repository from GitHub into the "project" directory.
