shell中嵌套执行expect命令实例（利用expect实现自动登录）

expect是

#!/bin/bash
passwd='123456'
/usr/bin/expect <<EOF
set time 30
spawn ssh root@192.168.76.10
expect {
"*yes/no" { send "yes "; exp_continue}
"*password:" {send "$passwd "}
}
expect "*#"
send "cd /tmp "
expect "*#"
send "echo 222 > 2.txt "
expect "*#"
send "df -h "
expect "*#"
send "free -m "
expect "*#"
send "ps -ef | grep httpd "
expect "*#"
send "quit "
interact

expect eof
EOF
