问题描述
为了更好地识别命令行上的输出的开始和结束，我想更改提示的颜色，以使它与程序输出明显不同。
To recognize better the start and the end of output on a commandline, I want to change the color of my prompt, so that it is visibly different from the programs output. As I use zsh, can anyone give me a hint?
推荐答案
下面是一个如何设置红色提示的示例：
Here's an example of how to set a red prompt:
PS1=$'\e[0;31m$ \e[0m'
魔法是 \e [0; 31m （打开红色前景） \e [0m （关闭字符属性）。这些被称为转义序列。不同的转义序列给出了不同的结果，从绝对光标定位到颜色，以及能够更改窗口的标题栏等。
The magic is the \e[0;31m (turn on red foreground) and \e[0m (turn off character attributes). These are called escape sequences. Different escape sequences give you different results, from absolute cursor positioning, to color, to being able to change the title bar of your window, and so on.
