How to Use the Command 'wifi-menu' (with Examples)

The wifi-menu command offers a straightforward way for users to establish a wireless network connection on Linux-based systems, specifically those running the Arch Linux distribution. This command is particularly beneficial for systems without a graphical user interface. It provides an interactive menu-driven interface where users can scan for available networks, select a preferred network, and input necessary credentials such as passwords. In scenarios where visible access points are present, wifi-menu presents an efficient method to connect without delving into complex network configurations.

Use Case 1: Set Up a Wireless Connection Interactively

Code:

wifi-menu

Motivation:

Using the wifi-menu command without additional arguments is perfect for users who want to quickly and effortlessly connect their device to a wireless network. This is particularly useful for those who are new to Linux or do not wish to manually configure network interfaces and details through configuration files. By offering an interactive text menu, users can visualize the available networks and easily select one to connect to, simplifying the entire process.

Explanation:

Running wifi-menu without any arguments initiates the command’s default behavior, which is to scan for nearby wireless networks and subsequently present the user with a menu of detected networks. This interactive menu allows the user to select a network from the list by navigating through it with keyboard arrows. Upon selecting a network, the user is prompted to enter a password or passphrase if required. It automates the configuration of the wireless settings within the background, thus establishing connectivity.

Example Output:

Starting wifi-menu...
Scanning for networks...
Please select a network:
1) MyHomeNetwork
2) WorkWifi
3) CoffeeShopWiFi
Enter number (1-3): 

Use Case 2: Interactively Set Up a Connection to a Network and Obscure the Password

Code:

wifi-menu --obscure

Motivation:

In environments where security is paramount, or in public settings where shoulder surfing could compromise sensitive information, using wifi-menu with the --obscure option adds an additional layer of privacy. By obscuring the password entry, this option helps users ensure that their Wi-Fi credentials remain confidential and safe from prying eyes. It’s especially beneficial in workplaces or public locations like cafes where multiple people might be present around the user.

Explanation:

The --obscure flag acts as a modifier to the standard wifi-menu command, altering how the password input is displayed during the connection setup process. Instead of showing the plaintext password when the user types it, each character is replaced by an asterisk or hidden entirely from view. This ensures that the password is not visible on the screen, protecting it from unauthorized disclosure.

Example Output:

Starting wifi-menu...
Scanning for networks...
Please select a network:
1) MyHomeNetwork
2) WorkWifi
3) CoffeeShopWiFi
Enter number (1-3): 1
Enter the password for 'MyHomeNetwork': ******
Connecting to MyHomeNetwork...

Use Case 3: Display Help

Code:

wifi-menu --help

Motivation:

Every command line user, at some point, requires guidance or clarification on how to utilize a command effectively. The --help option serves as an essential feature for providing immediate, inline help documentation. This is invaluable for both beginners and experienced users who wish to understand the scope of wifi-menu’s capabilities, explore additional options or simply seek a refresher on how to execute the command properly.

Explanation:

By executing wifi-menu --help, the system invokes the command’s built-in help functionality. This displays a help message that includes a list of available command options, a brief description of each option, and usage examples. Users can refer to this information to expand their knowledge about manipulating wifi-menu or to resolve any uncertainties regarding its usage in various contexts.

Example Output:

Usage: wifi-menu [options]

Interactively connect to a wireless network.

Options:
  --obscure    Obscure password entry
  --version    Show version information
  --help       Show this help message

Conclusion:

Understanding how to effectively use the wifi-menu command can considerably simplify the process of connecting to wireless networks on systems where graphical network managers are unavailable or undesired. Through its interactive interface, users can effortlessly establish connections, benefit from enhanced password privacy, and access on-demand user support through its help option. Whether a user is simply setting up their home network or ensuring confidentiality in a public setting, wifi-menu serves as a powerful tool in the Linux command-line toolkit.
