实验4 传递指定文件参数修改

sys.argv

一个列表，其中包含了被传递给 Python 脚本的命令行参数。 argv[0] 为脚本的名称（是否是完整的路径名取决于操作系统）。如果是通过 Python 解释器的命令行参数 -c 来执行的， argv[0] 会被设置成字符串 '-c' 。如果没有脚本名被传递给 Python 解释器， argv[0] 为空字符串。

为了遍历标准输入，或者通过命令行传递的文件列表，参照 fileinput 模块

import paramiko
import time
import getpass
import sys
username = input("Username: ")
password = getpass.getpass("Password: ")
ip_file = sys.argv[1]
cmd_file = sys.argv[2]
iplist = open(ip_file,'r')
for line in iplist.readlines():
    ip = line.strip()
    ssh_client = paramiko.SSHClient()
    ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh_client.connect(hostname=ip, username=username, password=password, look_for_keys=False)
    print('=-=-=-=-=-=-=-=-=-=-=-=-=-=')
    print('已经成功登陆交换机 ' + ip)
    command = ssh_client.invoke_shell()
    cmdlist = open(cmd_file, 'r')
    cmdlist.seek(0)
    for line in cmdlist.readlines():
        each_command = line.strip()
        command.send(each_command + 'n')
        time.sleep(5)
    cmdlist.close()
    output = command.recv(65535).decode('ASCII')
    print(output)
    ssh_client.close()
