expect

expect: command not found

执行：

yum -y install expect

从最简单的层次来说，Expect用来实现计算机之间需要建立连接时进行特定的登录会话、

function login(){
    echo "in"
    expect_sh=$(expect -c "
    spawn kinit ${LOGIN_USER_NAME}
    expect \"*assword*BAIDU.COM:\"
    send \"${LOGIN_USER_PASSWORD}\r\"
    expect \"#\"
    ")

    echo "$expect_sh"
}
#expect -c '
#spawn kinit hdfs
#expect "*assword*BAIDU.COM:"
#send "password123\r"
#expect "#"
#'
