使用 nmcli 在 ubuntu 中切换网络的脚本

我正在尝试使用nmcli使用 bash 文件在已填充的网络之间进行切换，但我得到了无意义的数据。

不过废话少说

代码如下。

#!/bin/bash

# Pre-populated UUID data for network connections
networks=(
    ["tr_5"]="127f3e9e-34dd-444e-aee4-7c2b35c7c307"
    ["VC_HotSpot_6"]="c498aa6a-24d4-4b51-92c7-9b8d84181fc1"
    ["Network_3"]="34567890-3456-3456-3456-345678901234"
)

# List available network connections
echo "Available network connections:"
nmcli connection show

# Prompt the user to choose a network
echo "Select the network to connect to:"
select network_name in "${!networks[@]}"; do
    if [[ -n $network_name ]]; then
        break
    fi
done

# Get the UUID of the selected network
network_uuid=${networks[$network_name]}

# Check if the network UUID exists
if [[ -z $network_uuid ]]; then
    echo "Network '$network_name' UUID not found. Exiting..."
    exit 1
fi

# Disconnect from the current network (if connected)
current_connection=$(nmcli connection show --active | awk 'NR>1{print $1}')
if [[ -n $current_connection ]]; then
    echo "Disconnecting from the current network..."
    nmcli connection down $current_connection
fi

# Connect to the chosen network
echo "Connecting to network '$network_name'..."
nmcli connection up uuid $network_uuid

# Display the connection status
echo "Connection status:"
nmcli connection show --active | grep -E "($network_name|$current_connection)"

echo "Network switch completed successfully!"

我运行脚本 ./network_switch.sh
