这篇文章主要介绍了通过python连接Linux命令行代码实例,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

代码如下

#!/usr/bin/python

# -*- coding: utf-8 -*-

'''https://www.ibm.com/developerworks/cn/linux/l-cn-pexpect2/index.html'''

import pexpect

import types

username = "root"

ip = "192.168.***.***"

password = "****"

pex = pexpect.spawn('ssh %s@%s' % (username, ip))

def _check(pattern, timeout=120):

i = pex.expect(pattern, timeout=timeout)

return i

def sendcr(cmd):

if pex == None:

return 0

n = pex.send("%s\r" % cmd)

return n

def getexec(cmd):

child = pexpect.spawn(cmd)

child.expect(pexpect.EOF)

return child.before

if __name__ == '__main__':

checklist1 = [["(?i)Connection refused", False],

["(?i)Host key verification failed.", False],

["(?i)VENUSTECH AUDIT SYSTEM MA1000", True],

# ["(?i)#\[/]",True], # hpux

["(?i).+>", True], # windows

[".+[>$#]\s*$", True], # debian

["(?i)Last login", True],

["(?i)access denied", False],

["(?i)NT_STATUS_LOGON_FAILURE", False],

["(?i)are you sure you want to continue connecting", "yes"],

["(?i)authentication fail(?!ure)", False],

["(?i)connection closed by remote host", False],

["(?i)login failed", False],

["(?i)login incorrect", False],

["(?i)need to be root", False],

["(?i)no route to host", False],

["(?i)not found", False],

["(?i)Bad secrets", False],

["(?i)incorrect password", False],

["(?i)permission denied", False],

# ["(?i)terminal type",terminal_type],

["This private key will be ignored.", False],

["(?i)no route to host", False],

["(?i)press 'Enter' key to proceed", "\r"],

["(?i)Y/N", 'Y'],

[pexpect.EOF, False],

[pexpect.TIMEOUT, False],

["(?i)Enter passphrase for key .*:", password],

["(?i)assword", password],

["(?i)passwd", password],

["(?i)sername", username],

["(?i)(?

["(?i)----------------------------------------------------------------", True]]

checklist2 = [i[0] for i in checklist1]

while True:

i = _check(checklist2)

print i, checklist1[i], checklist1[i][1]

if (type(checklist1[i][1]) is types.BooleanType):

if type(checklist1[i][1]):

break

else:

sendcr(checklist1[i][1])

cmd = "ls -l /etc/rsyslog.conf"

result = getexec(cmd)

print "result", result

打印结果：

26 ['(?i)assword', '***'] ***

5 ['(?i)Last login', True] True

result -rw-r--r--. 1 root root 3167 Mar 13 11:24 /etc/rsyslog.conf
