在Python 3中,可以使用subprocess
模块来在Linux环境下进行进程管理
import subprocess
# 启动一个命令行程序(如ls)
process = subprocess.Popen(["ls"], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
# 获取子进程的输出
output, error = process.communicate()
if process.returncode != 0:
print(f"Error occurred: {error.decode('utf-8')}")
else:
print(f"Output: {output.decode('utf-8')}")
import subprocess
import time
# 启动一个命令行程序(如ls)
process = subprocess.Popen(["ls"])
# 等待子进程完成,并获取返回码
return_code = process.wait()
if return_code != 0:
print(f"Error occurred with return code {return_code}")
else:
print("Subprocess completed successfully")
import subprocess
import os
# 启动一个命令行程序(如ls)
process = subprocess.Popen(["ls"])
# 获取子进程的进程ID
pid = process.pid
# 检查子进程是否仍在运行
if os.path.exists(f"/proc/{pid}"):
print(f"Subprocess with PID {pid} is still running")
else:
print(f"Subprocess with PID {pid} has terminated")
import subprocess
import signal
# 启动一个命令行程序(如ls)
process = subprocess.Popen(["ls"])
# 向子进程发送SIGINT信号(如Ctrl+C)
process.send_signal(signal.SIGINT)
# 等待子进程终止
process.wait()
这些示例展示了如何使用Python 3的subprocess
模块在Linux环境下进行基本的进程管理。你可以根据需要调整这些示例以满足你的具体需求。
