bt: Wrapper for `bluetoothctl` that allows shortest-prefix for device name and command

bt.sh

#!/bin/env bash

device=$(bluetoothctl paired-devices | grep -iE "$1" | cut -d' ' -f2)
if [[ -n $2 ]]; then
    command=$(bluetoothctl help | cut -d' ' -f1 | grep -iE "$2" | head -n1 | perl -pe 's/\e([^\[\]]|\[.*?[a-zA-Z]|\].*?\a)//g')
else
    command="connect"
fi
echo "Command: bluetoothctl $command $device"

bluetoothctl "$command" "$device"

Assuming device named "Device":
bt dev connects
bt dev discon disconnects
