LINUX下SHELL显示-BASH-4.1$不显示路径的解决方法

linux shell中不显示路径，使用起来很不方便。
如何更改外壳以显示路径？

进行如下操作：

vi ~/.bash_profile

（不管.bash_profile文件有多少，也可以自己新建一个）

在末尾添加：

导出 PS1='[\u@\h \W]\$'

然后执行

源?/ .bash_profile

这样shell可以显示路径

(The path is not displayed in the Linux shell, which is very inconvenient to use.
How do I change the shell to show the path?
Do the following:
vi ~/. bash_ profile
(no matter how many. Bash_profile files there are, you can also create one by yourself)
Add at the end:
Export PS1 = '[\ u @ \ h \ w] \ $'
Then execute
Source? / bash_ profile
This allows the shell to display the path
)
