SendKeys

SendKeys is a Bash script that allows you to send keystrokes to a selected virtual machine (domain) managed by virsh.

What It Does

• Domain Selection: The script fetches all available domains from virsh (skipping header lines) and displays them as a numbered list.
• User Prompt: It asks the user to select one of these domains by entering the corresponding number.
• Keystroke Simulation: Once a domain is selected, the script reads text input from the user. For each character in the input, it looks up the corresponding USB HID key code from a predefined associative array.
• Sending Keystrokes: The script sends the matched key codes to the selected domain using the sudo virsh send-key command.

How to Use

1. Prerequisites:

   • Ensure you have the virsh command available (as part of the libvirt package).
   • Run the script with the necessary permissions to use sudo.

2. Run the Script:
   Open your terminal and execute:

   ./sendkeys.sh

3. Follow On-Screen Prompts:

   • Select a domain by entering the corresponding number.
   • Enter the text you would like to send. Each keystroke will be transmitted to the chosen domain.

Additional Notes

• The script continuously prompts for text input until it is manually terminated.

• It handles a variety of characters including lowercase and uppercase letters, numbers, and special characters by mapping them to their USB HID key codes.
