linux - Can Linux Bash scripts respond to install options

Question

I need to script the installation of a number of products on Redhat Linux I am installing from previously downloaded tar files that each contain their own specific install.sh. My problem is that by executing the install.sh scripts a number of questions are asked such as ...
a). Accept license
b). set default path(s)
c). do i wish to start service
etc...
Can Bash detect these questions and respond correctly? or do i require another linux based product/function?
For windows based installs i have used AutoItScript. What are my options on Linux Redhat?

Answer 1

要确定脚本是否支持任何命令行选项，您可以：

• 阅读软件的自述文件，如果有的话。这应该解释任何选项。
• install.sh阅读脚本的顶部。通常选项至少在那里列出。
• 阅读代码本身，这可能是很多工作。

一旦确定脚本不支持选项，自动执行此操作的标准方法是使用expect脚本。例如，请参阅使用期望脚本自动化 install.sh 脚本。

根据安装脚本的工作方式，您可以通过标准输入向它发送命令。例如，如果您按Tab一次，然后按 ，Enter然后y再按一次Enter，您可以尝试以下操作：

printf %s $'\t\ny\n' | ./install.sh
