#!/usr/bin/expect

set timeout 30

if { [llength $argv] < 2} {

    puts "Usage:"

    puts "$argv0 local_file remote_path"

    exit 1

}

#argv 0表示第一个参数

#[lindex $argv n]获得index为n的参数（index从0开始计算

set local_file [lindex $argv 0]

set remote_path [lindex $argv 1]

set passwd GDJTxxzx123

set passwderror 0

spawn scp -r $local_file $remote_path

expect {

    "*assword:*" {

        if { $passwderror == 1 } {

        puts "passwd is error"

        exit 2

        }

        set timeout 1000

        set passwderror 1
