subprocess 是 Python 中执行操作系统级别的命令的模块,所谓系级级别的命令就是如ls /etc/user ifconfig 等和操作系统有关的命令。 subprocess 创建子进程来执行相关命令,并连接它们的输入、输出和错误管道,获取它们的返回状态。 1|1subprocess 来源 Subprocess模块开发之前,标准库已有大量用于执行系统级别命令的的方法...
在Python中,可以使用subprocess模块来执行命令,并获取命令的输出结果。下面是一个示例代码: importsubprocessdefis_process_running(process_name):cmd='tasklist'ifplatform.system()=='Windows'else'ps aux'output=subprocess.check_output(cmd,shell=True).decode()returnprocess_nameinoutput 1. 2. 3. 4. 5. 6...
def check_process_running(process_name): # 使用ps命令检查进程是否存在 cmd = "ps aux | grep {}".format(process_name) output = subprocess.getoutput(cmd) # 检查输出结果中是否包含进程名 if process_name in output: return True else: return False ...
import subprocess import time def check_and_close_program(program_name): process = subprocess.Popen(["pgrep", program_name], stdout=subprocess.PIPE, stderr=subprocess.PIPE) stdout, stderr = process.communicate() if process.returncode == 0: print(f"{program_name} is running, closing it...
Python脚本可以通过调用系统命令来检查特定的Linux命令是否仍在运行。下面是一个示例脚本: 代码语言:txt 复制 import subprocess def check_command_running(command): # 使用subprocess模块调用系统命令 result = subprocess.run(['pgrep', '-f', command], capture_output=True, text=True) if result.returncode ...
subprocess.run(pylint_command, shell=True) # Run flake8 print("\nRunning flake8...") flake8_command =f"flake8{file_path}" subprocess.run(flake8_command, shell=True) if__name__ =="__main__": directory =r"C:\Users\abhay\OneDrive\Desk...
exit code 1 [end of output] note: This error originates from a subprocess, and...
Popen is the underlying class for the whole subprocess module. All functions in the subprocess module are convenience wrappers around the Popen() constructor and its instance methods. Near the end of this tutorial, you’ll dive into the Popen class. Note: If you’re trying to decide whether ...
