A bash script to quickly disable your laptop keyboard when your cat decides to sit on it while you're using an external keyboard. Make it executable: `chmod +x cat_mode.sh`, bind it to an F key, adjust keyboard ID (run xinput list to find yours)

cat_mode.sh

#!/bin/bash

# Cat Mode Toggle Script
# Detects current state and toggles between enabled/disabled keyboard

KEYBOARD_ID=28
MASTER_ID=3

# Function to check if keyboard is currently floating (disabled)
is_keyboard_disabled() {
    # Check if keyboard is floating by looking at xinput list
    xinput list | grep -q "id=$KEYBOARD_ID.*floating slave"
    return $?
}

# Function to disable keyboard (activate cat mode)
disable_keyboard() {
    # Disable the keyboard
    xinput float $KEYBOARD_ID
    
    # Show notification
    notify-send "Cat Mode Activated" "Keyboard disabled for 30 minutes" -i input-keyboard
    
    echo "Keyboard disabled. It will automatically re-enable in 30 minutes."
    echo "To manually toggle back, press F8 again or run this script."
    
    # Schedule automatic re-enable in 30 minutes (1800 seconds)
    (sleep 1800 && xinput reattach $KEYBOARD_ID $MASTER_ID && notify-send "Cat Mode Deactivated" "Keyboard automatically re-enabled" -i input-keyboard && rm -f $TIMER_PID_FILE) &
    
    # Store the background job PID
    echo $! > $TIMER_PID_FILE
    echo "Timer PID: $! (saved to $TIMER_PID_FILE)"
}
