linux expect 自动登录交换机保存配置

telnet.exp 文件内容如下：

#!/usr/bin/expect -f  set ip [lindex $argv 0 ]       set username [lindex $argv 1 ]      set password [lindex $argv 2 ]     set superpassword  [lindex $argv 3 ]  set timeout 10                     spawn telnet $ip expect { "name" { send "$username\r";exp_continue } "*assword" { send "$password\r"; exp_continue } "*>" { send "enable\r" ; exp_continue } }expect { "*assword" { send "$superpassword\r"; exp_continue } "*#" { exp_send "wr \r";} }exp_send "quit\r"expect eof

命令执行：
