python脚本中使用pexpect模块实现远程SSH登录,登陆成功后显示/home目录文件清单,并通过日志文件记录所有的输入与输出。

#!/usr/bin/env python
import pexpect
import sys

child=pexpect.spawn('ssh xxxxx@192.168.42.2')
fout=file('mylog1.txt','w')
child.logfile=fout

child.expect("password:")
child.sendline("xxxxx")
child.expect('$')
child.sendline('ls /home')

运行结果:
xxxxx:pythontest/ $ python simple1.py
xxxxx:pythontest/ $ cat mylog1.txt
xxxxxx@192.168.42.2's password: xxxxxx
ls /home

期望运行结果:
xxxxx:pythontest/ $ cat mylog1.txt
xxxxxx@192.168.42.2's password: xxxxxx
ls /home
xxx xxxx.zshrc

问题以解决:child.expect(pexpect.EOF)
