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...

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 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...
