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 = [["(", False],
["(", False],
["(", True],
# ["(",True], # hpux
["(", True], # windows
[".+[>$#]\s*$", True], # debian
["(", True],
["(", False],
["(", False],
["(", "yes"],
["(", False],
["(", False],
["(", False],
["(", False],
["(", False],
["(", False],
["(", False],
["(", False],
["(", False],
["(", False],
# ["(",terminal_type],
["This private key will be ignored.", False],
["(", False],
["(", "\r"],
["(", 'Y'],
[pexpect.EOF, False],
[pexpect.TIMEOUT, False],
["(", password],
["(", password],
["(", password],
["(", username],
["(", username],
["(", 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
