Question

我有以下脚本允许我登录到不同的路由器并运行不同的命令，然后将它们输出到文件中，除了我为每个路由器获取一个文件之外，这很有效。所以我要做的就是看看我是否只能获得一个文件，无论我进入多少个盒子。我使用host.txt文件来定义路由器和commands.txt来定义我想要运行的命令。

import telnetlib

user = "user"
password = "password"


#Getting list of Sites to use and logging in
with open('host.txt', 'r') as hostlist:
    host = [line.strip() for line in hostlist]
    for hostname in host:
        tn = telnetlib.Telnet(hostname,23,30)
        print "Grabbing data from site"
        tn.read_until("Username: ")
        tn.write(user + "\n")
        tn.read_until("Password: ")
        tn.write(password + "\n")
        tn.write("\n")
        tn.write("term length 0\n")
        with open('commands.txt', 'r') as commandlist:
            commands = [line.strip() for line in commandlist]
            for commandcall in commands:
                tn.write(commandcall + "\n")
        tn.write("exit\n")
        outFile = open(hostname + ".txt", "wt")
        outFile.write (tn.read_all())
        outFile.close()
        tn.close()

Answer 1

你有：

host = [line.strip() for line in hostlist]
for hostname in host:

然后：

outFile = open(hostname + ".txt", "wt")
outFile.write (tn.read_all())
outFile.close()

因此，每个主机名都将生成一个新文件是有道理的，因为您在循环时将outFile.open（）的参数更改为每个主机名。

如果你为open（）创建一个静态字符串的参数，这应该做你想要的。您还想使用＆＃34; a＆＃34;追加。

outFile = open("RouterLog.txt", "a")
outFile.write (tn.read_all())
outFile.close()

每个循环写一个文件vs python中的许多文件
