不用等待期望脚本中的用户输入 [英] gets not waiting for user input in expect script

问题描述

当我尝试运行以下期望脚本时，它只是完成运行，而是等待用户输入.有人可以告诉我我在做什么错吗?

When i try to run the following expect script, it just finishes running instead waiting for user input. Could someone tell me what i am doing wrong?

#!/usr/bin/expect
puts -nonewline stdout "Enter device id:"
flush stdout
gets stdin id
puts -nonewline  stdout "Enter device name:"
flush stdout
gets stdin name

推荐答案

Expect更改了Tcl gets命令，以使其不等待标准输入.要在等待时读取一行，您需要执行此操作，而不是gets stdin id:

Expect alters the Tcl gets command so that it doesn't wait for standard input; to read a line while waiting for it, you need to do this instead of gets stdin id:

# Read input to stdin
expect_user -re "(.*)\n"
set id $expect_out(1,string)
