qrwifi - Generate Wi-Fi QR Codes (macOS Only)

Description

qrwifi is a command-line utility designed exclusively for macOS that generates QR codes for easy Wi-Fi network access. It simplifies the process of sharing Wi-Fi credentials by creating a QR code that can be scanned by a mobile device or other QR code reader. The script retrieves the SSID and password (from the macOS keychain) and encodes them into a QR code.

Installation

1. Install qrencode: This script requires the qrencode command-line tool to generate the QR code images. Install it using your system's package manager:

   • macOS (using Homebrew): brew install qrencode

2. Save the script: Save the qrwifi.sh script to a suitable location (e.g., your home directory or /usr/local/bin).

3. Make the script executable: chmod +x qrwifi.sh

Usage

  Usage: qrwifi [OPTIONS]

  Generate a Wi-Fi QR code for easy network access.

  Options:
    -s, --ssid <SSID>       Specify the SSID. If not provided, attempts to
                            detect the current SSID.
    -p, --password <PASSWORD>  Specify the password for the network.
    -o, --output <FILE>     Specify the output file for the QR code image
                            (e.g., qr.png).  Defaults to stdout.
    -q, --quiet             Only output the password.
    -V, --version               Show the version and exit.
    -h, --help              Show this help message and exit.

  Examples:
    qrwifi -s MyWiFi -p MyPassword
    qrwifi -s MyWiFi -p MyPassword -o wifi.png

  Note:
    - If SSID is not provided, the utility will attempt to detect the current
      SSID. This may require appropriate permissions.
    - Requires the 'qrencode' command-line tool to be installed.
