如何既能捕获shell命令输出，又能在终端实时显示？

#!/bin/bash

command="your_shell_command"
tmp_file="/path/to/temp/file"

# 执行shell命令并将输出重定向到临时文件
$command > $tmp_file

# 实时显示临时文件内容
tail -f $tmp_file

import subprocess
import sys

def execute_command(command):
    process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, shell=True)
    while True:
        output = process.stdout.readline()
        if process.poll() is not None:
            break
        if output:
            print(output.strip().decode(sys.stdout.encoding))
    if process.returncode == 0:
        return True
    else:
        return False

command = "your_shell_command"
execute_command(command)
