提示输入使用grunt-shell插件 [英] Prompt for input in using the grunt-shell plugin

问题描述

我有一个脚本，正在尝试使用grunt-shell插件与grunt一起运行.该脚本使用read -p "enter foo" bar提示输入.当我运行它时，我得到一个光标，该光标正确地接受了我的输入，但是看不到"enter foo".

I have a script I am trying to run with grunt using the grunt-shell plugin. This script prompts for input using read -p "enter foo" bar. When I run it, I get a cursor that correctly takes my input, but I don't see "enter foo".

我尝试修改grunt-shell配置以将err，stderr和stdout转储到控制台，但是一旦命令完成，它们都将变为空. read的手册页中提到-p标志仅当输入来自终端时才显示提示."这似乎是我的问题，因为节点正在调用提示，但是read命令正在我的命令行中执行终端，而我正在终端中输入输入，那为什么不起作用?

I tried modifying the grunt-shell config to dump err, stderr, and stdout to the console, but they all come out empty once the command completes. The man page for read says about the -p flag "The prompt is displayed only if input is coming from a terminal.", which seems like it may be my issue since node is calling the prompt, but the read command is executing in my terminal, and I am entering input in a terminal, so why wouldn't that work?

所以，我的问题是，有什么方法可以提示用户从grunt-shell插件输入吗?

So, my question is, is there any way to prompt for user input from the grunt-shell plugin?

此外，作为一个PS，是的，我知道仅回显提示并处理其下方的输入将非常容易，但是该死的是原理.

Also, as a P.S., yes i know it would be very easy to just echo the prompt and deal with the input being below it, but dammit it's the principle of the thing.

推荐答案

我将代码重定向回/dev/tty. 以bash -c run.sh </dev/tty

I redirected my code back to /dev/tty. Ran it as bash -c run.sh </dev/tty
