场景：
shell脚本中，scp和ssh连接时，自动输入用户名和密码。

#!/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"
