在Python中,可以使用多线程或者多进程来实现并发执行shell命令。
import threading
import subprocess
def execute_shell_command(command):
subprocess.call(command, shell=True)
threads = []
# 创建多个线程,每个线程执行一个shell命令
commands = [
"echo 'Hello, World!'",
"ls -l",
"ping www.google.com"
]
for command in commands:
thread = threading.Thread(target=execute_shell_command, args=(command,))
threads.append(thread)
thread.start()
# 等待所有线程执行完毕
for thread in threads:
thread.join()
import multiprocessing
import subprocess
def execute_shell_command(command):
subprocess.call(command, shell=True)
processes = []
# 创建多个进程,每个进程执行一个shell命令
commands = [
"echo 'Hello, World!'",
"ls -l",
"ping www.google.com"
]
for command in commands:
process = multiprocessing.Process(target=execute_shell_command, args=(command,))
processes.append(process)
process.start()
# 等待所有进程执行完毕
for process in processes:
process.join()
以上两种方法都是通过循环创建多个线程或进程,每个线程或进程执行一个shell命令,并使用join()方法等待所有线程或进程执行完毕。注意,使用多线程或多进程执行shell命令时,需要注意线程或进程间可能存在的竞争条件和资源共享问题。
