您好我正在尝试从外部文件向Cisco / Juniper路由器发送多个show命令。我有要求这样做...但由于某种原因，我一直有一个发送所有内容的问题。我试图用pxpect做这个。如果我想要运行10个show命令，我只能获得2或3 ...任何帮助？这是Python。
import sys,pexpect,getpass,time
username = raw_input("Username: ")
password = getpass.getpass()
routerFile = open('devicelist', 'r')
routers = [i for i in routerFile]
for router in routers:
try:
child = pexpect.spawn ('telnet', [router.strip()])
child.expect(['[uU]sername:', '[lL]ogin:'], timeout=3)
child.sendline(username)
child.expect('[pP]assword:')
child.sendline(password)
software = child.expect([ '#'], 6)
print ("Logging into " + router.strip())
except:
print "\nCould not log in to " + router.strip()
pass
commandlist = 'junos'
commands = open(commandlist, 'r')
for command in commands:
command.strip()
child.sendline(command.strip())
child.expect(['>'],20)
print child.before
这些是我试图发送的命令：
show interface terse | no-more | match lo
show interfaces descriptions
show interfaces descriptions
show interfaces lo0.0 | match local
show route | match mpls
show system uptime | match boot
这是输出..从未完成......
