在bash脚本提示后如何编程输入? [英] How do I programmatically input after a prompt with bash script?

问题描述

我必须运行bash脚本bash.sh，该脚本启动命令行工具.

I have to run a bash script bash.sh that starts up a command line tool.

该命令行工具提示输入Please enter your email:

That command line tool has a prompt that says Please enter your email:

然后，我需要一种在提示后以编程方式输入我的电子邮件的方法.

I then need a way to programmatically enter my email after the prompt.

我只是尝试了[e-mail]而我已经尝试了echo [e-mail].似乎都不起作用，因为提示不允许我再运行任何命令.

I have tried simply [e-mail] and I have tried echo [e-mail]. Neither seem to work because the prompt does not allow me to run any more commands.

这可行吗?

推荐答案

将其传递给stdin:

Pass it to stdin:

command_line_tool <<< "[e-mail]"
