DNCheckBashScript

This repository contains a Bash script designed to help users manage and inspect their Docker network environments. The script provides an easy-to-use command-line tool to list all Docker networks on a system and identify whether they are in use by any containers.

Features

• Network Usage Detection: The script loops through all Docker networks and prints out whether each network is currently being used by running or stopped containers.
• Default Network Skipping: It intelligently skips default Docker networks (bridge, host, none) to prevent unnecessary alerts, as these networks are typically used by Docker internally.
• Container Listing: For networks that are in use, the script lists all associated container IDs and names, providing a detailed view of the network's utilization.
• jq Auto-Installation: The script checks if jq (a lightweight and flexible command-line JSON processor) is installed on the system and attempts to install it if it's missing.

Prerequisites

• Docker installed and running on your system
• Bash shell environment
• Sudo privileges (if jq is not installed and needs to be automatically installed by the script)
