Here is an updated basic bash script originally created by ummeegge, which is designed for basic network and system monitoring. The updated version now checks for necessary addons and installs them if not found, among other improvements.

What is required

Some addons, as mentioned the script now checks for and installs them if they are not found using Pakfire.

# Run monitoring tools
run_tool "saidar" "See what your system's up to."
run_tool "bwm-ng" "How's the bandwidth?"
run_tool "iftop" "Who's hogging the network?"
run_tool "htop" "What are your processes doing?"

# Exit
echo -e "${CYAN}Details: $current_date, IP: $ip_address, Host: $hostname${RESET}"
echo "End"

After dropping / creating the script must be made executable:

chmod +x network_info.sh
