Python中执行CMD命令的方法总结

import subprocess

# 执行简单的CMD命令
result = subprocess.run("dir", shell=True, capture_output=True, text=True)
print(result.stdout)

import subprocess

# 执行CMD命令并获取输出
result = subprocess.run("ipconfig", shell=True, capture_output=True, text=True)

# 处理输出
if result.returncode == 0:
    lines = result.stdout.splitlines()
    for line in lines:
        print(line)
else:
    print(f"命令执行失败：{result.stderr}")

import subprocess

# 执行带有参数的CMD命令
result = subprocess.run(["echo", "Hello, Python!"], capture_output=True, text=True)
print(result.stdout)

import subprocess

# 异步执行CMD命令
process = subprocess.Popen(["ping", "www.google.com"], stdout=subprocess.PIPE, text=True)

# 读取命令输出
while True:
    output = process.stdout.readline()
    if output == '' and process.poll() is not None:
        break
    if output:
        print(output.strip())

import subprocess

try:
    # 尝试执行CMD命令
    result = subprocess.run("unknown_command", capture_output=True, text=True, check=True)
    print(result.stdout)
except subprocess.CalledProcessError as e:
    print(f"命令执行失败，错误信息：{e.stderr}")
except FileNotFoundError:
    print("未找到命令，请检查命令是否存在。")

import subprocess
import shlex

# 动态生成命令字符串
command_str = "echo Hello, Python!"
command_list = shlex.split(command_str)

# 执行命令
result = subprocess.run(command_list, capture_output=True, text=True)
print(result.stdout)

import os

# 使用os模块执行CMD命令
os.system("dir")

import shutil

# 复制文件
shutil.copy("source.txt", "destination.txt")

import subprocess
import shlex

# 动态生成命令字符串并确保安全性
command_str = "echo Hello, Python!"
safe_command_str = shlex.quote(command_str)

# 执行命令
result = subprocess.run(safe_command_str, shell=True, capture_output=True, text=True)
print(result.stdout)

import subprocess
from concurrent.futures import ThreadPoolExecutor

# 定义多个CMD命令
commands = ["dir", "echo Hello", "ipconfig"]

# 并行执行CMD命令
with ThreadPoolExecutor() as executor:
    results = list(executor.map(subprocess.run, commands, capture_output=True, text=True))

# 处理执行结果
for idx, result in enumerate(results):
    print(f"命令 {commands[idx]} 的输出：\n{result.stdout}")
