场景：

shell脚本中，scp和ssh连接时，自动输入用户名和密码。

解决方案：

例：

#!/bin/bash
remoteIp=IP
remoteUser=用户名
remotePw=密码

function download(){
  remoteFile=$1
  localDir=$2
  expect << EOF
    set timeout 1200;
    spawn scp -r -p $remoteUser@$remoteIp:"$remoteFile" "$localDir"
    expect{
      "*yes/no*" {send "yes\n";exp_continue}
      "*Permission denied*" {exit 1}
      "*password*" {send "$remotePw\n";exp_continue}
      "*Killed by signal 1" {exit 1}
    }
EOF
}

fucntion remoteCmd(){
  cmd=$1
  expect << EOF
    set timeout 1200;
    spawn ssh $remoteUser@$remoteIp
    expect{
      "*yes/no*" {send "yes\n";exp_continue}
      "*Permission denied*" {exit 1}
      "*password*" {send "$remotePw\n";exp_continue}
      "*\$ " {send "\n"}
    }
    expect "*\$ " {send "$cmd\n"}
    expect "*\$ " {send "exit\n"}
EOF
}

remoteCmd "ls -l"
