Getting Started

This guide explains how to use the Drone Data Management Application script to execute commands across multiple drones in a network. The script supports primary and secondary drone groups with different users.

Note: The script is designed for drone fleet management with SSH access. Ensure your system meets the prerequisites before running the script.

Before you start

Make sure that:

• You have Bash installed (default on most Unix-like systems)
• SSH access is configured for target drones
• The script file (main.bash) has execute permissions (chmod +x main.bash)

Usage Guide

1. Prepare the script
   Ensure the script is executable:

   chmod +x main.bash

2. Run the script with arguments
   Supported arguments:

   • -primary, -ip: List of IP addresses for primary group
   • -puser, -user: Username for primary group
   • -secondary: List of IP addresses for secondary group
   • -suser: Username for secondary group
   • -cmd: Command to execute on all drones (use \$DRONE_NUM for drone number)

   Example:

   ./main.bash -primary 1 2 3 -user pilot -cmd "echo Drone \$DRONE_NUM ready"

3. Using Primary and Secondary Groups
   You can execute commands on two different groups with different users:

   ./main.bash -primary 1 2 -user pilot1 -secondary 3 4 -suser pilot2 -cmd "status"

4. Allowed IP Ranges
   The script currently allows these IP suffixes:

   • Numbers 1-10
   • Number 15
   • Number 17
   • Numbers 20-25

   To modify allowed ranges, update the allowed_ips array in the script:

   allowed_ips=({1..10} 15 17 {20..25})

Error Handling

The script provides detailed error messages for:

• Invalid IP addresses
• IPs outside allowed ranges
• Duplicate IP addresses
• Missing required arguments
• Invalid command format

Tip: The script performs thorough validation before executing any SSH commands to prevent errors during execution.
