linux脚本之expect【机器交互】

yum install -y expect

lspawn              交互程序开始后面跟命令或者指定程序
lexpect 获取匹配信息匹配成功则执行expect后面的程序动作
lsend exp_send 用于发送指定的字符串信息
lexp_continue 在expect中多次匹配就需要用到
lsend_user 用来打印输出 相当于shell中的echo
lexit               退出expect脚本
leof expect执行结束 退出
lset 定义变量
lputs 输出变量
lset timeout        设置超时时间
