使用expect命令，该命令语法采用了tcl编程语言

#!/usr/bin/expect

set timeout 20
set ip "IP地址"
set user "账号"
set password "密码"

spawn ssh "$user\@$ip"

expect "$user@$ip's password:"
send "$password\r"

interact

使用SCP命令，自动输入密码

#!/usr/bin/expect

set timeout 3000

set server_host "IP地址"
set server_user "账号"
set password "密码"

set local_root "本地要上传的文件"
set server_root "上传的目标目录"

spawn scp -r $local_root $server_user@$server_host:$server_root

expect {
    "*password:" {
        send "$password\r"
        exp_continue
    }
    "*?" {
        send "y\r"
    }
}

expect eof

SCP循环使用，自动输入密码

#!/usr/bin/expect

set timeout 20
set server_host "IP地址"
set server_user "账号"
set password "密码"

set local_root "本地目录"
set server_root "目标目录"

while { [gets stdin line] >= 0 } {
    if {$line == "EOF"} {
        break
    }

    spawn scp -r $local_root$line $server_user@$server_host:$server_root$line
    expect "*password:"
    send "$password\r"

    expect eof
}
