linux - Bash 脚本响应控制台输出？

Question

当前正在尝试在启动时运行 bash 脚本来自动安装鱿鱼，但是我正在运行的命令需要输入。

目前我拥有的脚本是:

#!/bin/sh
PROXY_USER=user1
PROXY_PASS=password1
wget https://raw.githubusercontent.com/hidden-refuge/spi/master/spi && bash spi -rhel7 && rm spi
#After i run this command it asks "Enter username" 
#followed by "Enter password" and "Renter password"
echo $PROXY_USER
echo $PROXY_PASS
echo $PROXY_PASS
echo yes

但是我无法让输入工作，并且脚本无法创建用户名和密码。我运行的是 centos 7。

看看您正在调用一些以交互模式运行的工具，例如 dani-gehtdichnixan在 ( passing arguments to an interactive program non interactively ) 中提到，您可以使用 expect 实用程序。

在 debian 上安装 expect:

apt-get install expect

创建一个脚本调用spi-install.exp，如下所示:

#!/usr/bin/env expect
set user username
set pass your-pass

spawn spi -rhel7 
expect "Enter username"
send "$user\r"

expect "Renter password"
send "$pass\r"

然后在主 bash 脚本中调用它:

#!/bin/bash 
wget https://raw.githubusercontent.com/hidden-refuge/spi/master/spi  && ./spi-install.exp  && rm spi

Expect is used to automate control of interactive applications such as Telnet, FTP, passwd, fsck, rlogin, tip, SSH, and others. Expect uses pseudo terminals (Unix) or emulates a console (Windows), starts the target program, and then communicates with it, just as a human would, via the terminal or console interface. Tk, another Tcl extension, can be used to provide a GUI.
