Python中的OS特定命令 [英] OS specific command in Python
问题描述
我想编写一个python程序并在其中调用特定于OS的命令。
所以基本上，不要输入命令行参数我想要
它在python程序中让它执行操作。
例如。在我的程序中，我想调用ssh功能，例如
命令行上的功能
ssh Ad***@192.168.2.10 ... ..etc
我怎样才能轻松做到这一点？
我们非常感谢您的帮助。
谢谢

当您（通过ssh或telnet）连接到远程计算机时，您需要
类型（手动）
您的用户名和你的密码。编程绝非易事。
如果您需要的是模拟控制台交互，您将需要
获得期望。
Expect允许您根据工具命令语言（又名Tcl）在文本
控制台中编程/模拟用户交互。
但是有其他选择：启动一个写为shell的SSH守护进程
脚本。 （你只需要输入你的登录/传递一次，然后调用
守护进程执行一些命令）
恕我直言，期待是迄今为止最干净的方式。
问候，

有几种方法可以这样做：
* os.system（）如果你只是想发一个命令（那种火与忘记） ）
*子进程模块，如果你想访问stdin，stdout和stderr
的已启动命令

要与ssh进程交互，有一个很棒的模块叫做pexpect
（有一些如何在python中处理ssh进程的例子）

OT ：paramiko是一个在python中处理SSH2协议的模块

I want to write a python program and call OS specific commands in it.
So basically, instead of typing in on the command line argument I want
to have it in a python program and let it do the action.
for example. in my program I would want to call the ssh feature like
one does on the command line
ssh Ad***@192.168.2.10 .....etc
How can I do this easily ?
Every help is appreciated.
Thanks

Try exec() and execfile() from the standard library (IIRC)
for example. in my program I would want to call the ssh feature like
one does on the command line
ssh Ad***@192.168.2.10 .....etc
When you connect (via ssh or telnet) to a remote machine, you need to
type (manually)
your username and your password. Programming that is never easy.
If what you need is simulating console interaction, you will need to
get Expect.
Expect allows you to program/emulate user interaction in a text
console, based on the Tool Command Language (a.k.a. Tcl).
But there are alternatives : start a SSH daemon written as a shell
script. (you just have to enter your login/pass once, then call the
daemon to execute some commands)
IMHO, Expect is by far the cleanest way.

Stéphane

There are several ways to do so :
* os.system() if you just want to launch a command (kind of fire-and-forget)
* the subprocess module if you want to access stdin, stdout and stderr
of the launched command
for example. in my program I would want to call the ssh feature like
one does on the command line
ssh Ad***@192.168.2.10 .....etc
To interact with an ssh process , there is a great module called pexpect
(featuring some examples of how to handle ssh process in python)
