#!/usr/bin/expect spawn /usr/bin/ssh root@192.168.1.1expect "*password:" send "123456\r" expect "*]#" send "ifconfig\r" expect "*]#" send "exit\r" expect eof

实现ssh密码自动输入，并执行ifconfig命令：

spawn /usr/bin/ssh root@192.168.1.1 Address 192.168.1.1 maps to localhost, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT! root@192.168.1.1's password: Last login: Tue Mar 10 15:05:14 2015 from 192.168.1.2[root@test ~]# ifconfig eth0 Link encap:Ethernet HWaddr 00:50:56:A5:00:1A inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:235112063 errors:0 dropped:0 overruns:0 frame:0 TX packets:93490796 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:72881985355 (67.8 GiB) TX bytes:89899338679 (83.7 GiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:7443239 errors:0 dropped:0 overruns:0 frame:0 TX packets:7443239 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:5703083676 (5.3 GiB) TX bytes:5703083676 (5.3 GiB)
