Usage

This script can be used either by exporting environment variables or using user input after the script is executed.

Read at Runtime

This is the recommended way. Note that the bash function read is used. This does interpret the input, especially it does word splitting. So be careful with whitespaces. See bash(1) . If your password contains special characters you may want to use environment variables.

1. Execute the script:

   ./wifi-qr-gen.sh
   

2. Answer the prompts and confirm with <CR>. Note that you won't get visual feedback on the password prompt.

Environment Variables

Use this way if your password contains special characters and didn't worked with the first approach. You may want to set HISTCONTROL=ignoreboth and prefixing your commands with a whitespace to prevent having your password in the command history. See bash(1) for more information.

1. Set and export WLAN_SSID:

   WLAN_SSID="My cool WLAN name"
   export WLAN_SSID
   

2. Set and export WLAN_PASS:

    WLAN_SSID="My cool WLAN name"
   export WLAN_SSID
   

3. Execute the script:
