方法一、使用os模块的system方法:os.system(cmd),其返回值是shell指令运行后返回的状态码,int类型,0表示shell指令成功执行,256表示未找到,该方法适用于shell命令不需要输出内容的场景。 举例说明: 1. 列举当前目录下的所有文件。 1 importos2 val = os.system('ls -al')3 print val 没有找到时,sh返回的状态...
使用subprocess模块的目的是替代os.system()、os.popen*()、commands.*等旧的函数或模块。 3.1.subprocess.call(["some_command","some_argument","another_argument_or_path"]) subprocess.call(command,shell=True) 3.2.subprocess.Popen(command,shell=True) 假设command不是一个可运行文件。shell=True不可省。
os.popen(cmd): 这种调用方式是通过管道的方式来实现,函数返回一个file-like的对象,里面的内容是脚本输出的内容(可简单理解为echo输出的内容)。使用os.popen调用test.sh的情况: python调用Shell脚本,有两种方法:os.system(cmd)或os.popen(cmd),前者返回值是脚本的退出状态码,后者的返回值是脚本执行过程中的输出内...
A terminal is a MacOS command line interface (CLI) application that can be used to execute OS-level operations and run system commands. The terminal can be used to run code too. A language like Python or JavaScript’snode.jsallows you to write and run code directly from the terminal. So...
On Windows, the return value is that returned by the system shell after running command. The shell is given by the Windows environment variable COMSPEC: it is usually cmd.exe, which returns the exit status of the command run; on systems using a non-native shell, consult your shell documenta...
Using os.system to Run a Command Python allows us to immediately execute a shell command that's stored in a string using theos.system()function. Let's start by creating a new Python file calledecho_adelle.pyand enter the following:
if shell.recv_ready():output += shell.recv(65535).decode("utf-8")else:break# 关闭 SSH 连接ssh.close()# 提取配置内容(去除无关信息)config_lines = output.splitlines()config = "\n".join(config_lines[2:-1]) # 适配不同交换机,调整索引# 保存配置到文件timestamp = datetime.now().strftime...
The system function can also execute a bunch of commands. It executes every command that you can run in the terminal. We will use thetryblock, and inside this block, we will use thesystem()method, which will help us to interact with the operating system using the terminal. If thetrybloc...
