如何在命令后永久更改终端的外壳提示符颜色并创建新的空行？

Question

[在尝试进行更改之前，我有PS1="\n$PS1"。我的别名PS1="\e[0;34m[\u@ \W]\$ \e[m"中目前有.bash_profile，但它没有给我我想要的行为。当我编写命令并在完成之前到达该行的末尾时，终端不会继续前进到下一行。相反，它返回到我正在处理的行的开头，并在我继续键入时以视觉方式覆盖bash提示和之后的所有内容。当终端到达上一行的末尾时，如何使终端移动到新行，以及如何在每个命令之前/之后都将其留空？

[我试图将bash提示符颜色永久更改为蓝色，并在运行命令以使终端更易于阅读之后创建新的空行。

谢谢
