注意事项：expect的脚本运行需./*exp运行

set ipaddr [lrange $argv 0 0]    的理解

注：$argv0是脚本名，$argc表示参数的个数
[lindex $argv n]用来接收输入的脚本参数，n从0开始，分别表示第一个,第二个,第三个....参数，
[lindex $argv 0]是第一个参数也可以用[lrange $argv 0 0]表示, [lindex $argv 1]或者[lrange $argv 1 1]都可以表示第二个参数, 以此类推
[lrange $argv 0 4]表示第一个参数到第五个参数
send_user 用来显示信息到父进程(一般为用户的shell)的标准输出。
