shell脚本中expert交互

1 安装服务

yum install -y   expect 

2 案例（这里写成了函数，直接导入函数即可，还可以重定项输出！）

jx(){
expect <<EOF
    set time 30
    spawn vncpasswd
    expect {
        "Password:" { send "111111\r"; exp_continue }
        "Verify:" { send "111111\r"; exp_continue }
        "Would you like to enter a view-only password (y/n)?" { send "n\r" }
    }
    expect eof
EOF
}
