GetGit - Git Repository Setup Tool

A simple bash script that helps users set up SSH keys and clone repositories from a private git server.

Features

• SSH Key Generation: Automatically generates SSH keys if they don't exist
• Dynamic User Support: Works with any username on the git server
• Repository Discovery: Automatically discovers available repositories for the user
• Interactive Selection: Allows users to choose which repository to clone
• Dotfiles Support: Special handling for dotfiles repositories with automatic setup execution

Usage

1. Make the script executable:

   chmod +x setup.sh
   

2. Run the script:

   ./setup.sh
   

3. Follow the prompts:

   • Enter your git username
   • Generate SSH key (if needed)
   • Add the SSH key to your git account
   • Select which repository to clone

How It Works

1. Username Input

The script prompts for your git username, which is used to:

• Discover available repositories
• Construct repository URLs
• Set up proper directory structure

2. SSH Key Management

• Checks for existing SSH key (~/.ssh/id_ed25519)
• Generates a new key if none exists
• Displays the public key for copying to your git account

3. Repository Discovery

The script discovers ALL accessible repositories through multiple methods:

Primary Method - API Access:

• Attempts to use GitLab/Gitea API to fetch all repositories you have access to
• Includes both owned and shared repositories
• Automatically detects read/write permissions

Fallback Method - Pattern Scanning:

• Scans your own repositories: username/dotfiles, username/scripts, etc.
• Checks common shared repositories from users like: admin, shared, public, team, common, devops, infrastructure
• Discovers additional project repositories: website, api, frontend, backend, database, monitoring, etc.
• Tests SSH access to determine if you have read access to each repository

Repository Types Discovered:

• Your repositories: All repos you own
• Shared repositories: Repos you have read/write access to
• Public repositories: Publicly accessible repos on the server
• Team repositories: Organization/team repos you're a member of

4. Repository Selection

Users can:

• Select from numbered list of all discovered repositories (owned and shared)
• Press Enter to use username/dotfiles (if available)
• Type custom to enter a custom repository path
• See access type indicators: (owner), (shared), etc.

5. Cloning and Setup

• Clones the selected repository to the appropriate directory
• For dotfiles repositories: runs setup.sh automatically
• For other repositories: simply clones to ~/repository-name

Configuration

The script can be configured by modifying the settings at the top:

### === SETTINGS === ###
GIT_SERVER="git.del-c.net"  # Change to your git server

Directory Structure

• Dotfiles: ~/.dotfiles/
• Other repos: ~/repository-name/

Requirements

• Bash shell
• Git installed
• SSH client
• Access to the configured git server

Example Flow

$ ./setup.sh
[?] Enter your git username:
Username: john

[+] No SSH key found. Need to generate a new SSH key...
[+] If you are using the correct user, please enter your email for the SSH key.
Enter your email for the SSH key: john@example.com

----------------------------------------
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIGx... john@example.com
----------------------------------------
Press Enter after you've added the key...

[+] Fetching all accessible git projects...
[*] Attempting to fetch repositories via API...
[*] Found repositories via API:
1. john/dotfiles (owner)
2. john/scripts (owner)
3. team/shared-configs (shared)
4. admin/common-tools (shared)
5. public/templates (shared)

[?] Which project would you like to download?
Enter the number of the repository from the list above, or:
- Press Enter to use john/dotfiles (if available)
- Type 'custom' to enter a custom repository path

Enter your choice: 3
[*] Selected repository: git@git.del-c.net:team/shared-configs.git
[*] Download directory: /Users/john/shared-configs

[+] Cloning selected repository...
[*] Repository cloned successfully to: /Users/john/shared-configs

Troubleshooting

SSH Key Issues

• Ensure the SSH key is added to your git account
• Check SSH connection: ssh -T git@git.del-c.net

Repository Not Found

• Verify the repository exists on the server
• Check username spelling
• Ensure you have access to the repository

Permission Denied

• Confirm SSH key is properly added to git account
• Verify you have read access to the repository
