import subprocess

def execute_command(command):

    return output

def task_func(commands):
    """
    Executes a list of shell commands in parallel using multiprocessing, and collects their outputs.
    
    Parameters:
        commands (list): A list of shell commands to be executed.

    Returns:
        list: A list of byte strings, each representing the output of a command. Returns an empty list if `commands` is empty.

    Requirements:
    - subprocess
    - multiprocessing.Pool

    Notes:
    - If `commands` is an empty list, the function returns an empty list without attempting to execute any commands.
    
    Examples:
    >>> result = task_func(['ls', 'pwd', 'date'])
    >>> isinstance(result, list)
    True
    >>> all(isinstance(output, bytes) for output in result)
    True

instruct prompt

Executes a list of shell commands in parallel using multiprocessing, and collects their outputs.
Note that: Notes: If `commands` is an empty list, the function returns an empty list without attempting to execute any commands.
The function should output with:
    list: A list of byte strings, each representing the output of a command. Returns an empty list if `commands` is empty.
You should write self-contained code starting with:

Code

import subprocess
from multiprocessing import Pool
def execute_command(command):
    process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
    output, _ = process.communicate()
    return output
def task_func(commands):
