如何用换行显示阅读提示 [英] How to show read prompt with a new line

问题描述

我正在使用内置的 read 来读取变量，但是我想让输入出现在下一行，即提示输出了新行，但是两者都没有两部作品:

I'm using read builtin to read a variable, but I'd like to let the input appears on the next line, that is, the prompt output a new line, but neither of the two works:

$ read -p "Please input:\n" name
Please input:\n

$ read -p 'Please input:\n" name
Please input:\n

如您所见，即使在双引号的情况下，新行换码序列也不会被解释.所以有办法吗?

As you see new line escape sequence is not interpreted even in the double quote case. So is there anyway to do that?

推荐答案

您可以将提示与实际阅读内容分开:

You can separate the prompt from the actual read :

echo "Please input:"
read name

您可以将它们放在一行上:

You can put both on a single line :

echo "Please input:" ; read name

您还可以使用其他形式的引号:

You can also use a different form of quoting :

read -p $'Please input\n' name

这只是短短一点，许多人可能会觉得它的可读性较差，但这是一个品味问题.

This is barely shorter, and many would probably find it a bit less readable, but that is a matter of taste.
