Quick Start

1. Clone the repository

   git clone https://github.com/maheshbhatiya73/linux_system_scripts.git
   cd linux_system_scripts

2. Make scripts executable

   chmod +x */*.sh

3. Run a script

   ./system/first_boot_setup.sh

Usage

Each script can be run individually. Refer to the specific module documentation for detailed usage instructions:

• See kubernetes/README.md for Kubernetes setup
• See kubernetes/TELEGRAM_SETUP.md for notifications

Requirements

• Linux system (Ubuntu/Debian/CentOS)
• Bash 4.0+
• Root or sudo access (for most scripts)
• Internet connectivity (for package downloads)

Configuration

Most scripts include configuration files (.conf) in their respective directories. Customize these files before running scripts:

# Edit configuration
nano backup/backup.conf
nano kubernetes/kubernetes.conf

Contributing

When adding new scripts:

1. Follow the existing naming conventions
2. Include proper error handling and logging
3. Add configuration files for complex scripts
4. Document usage in module-specific README files
