Linux under Shell display-bash-4.1# does not show path resolution

The path is not shown in the Linux shell, and it is inconvenient to use it as a-bash-4.1#.

How do I change the shell to show the path?

The steps are as follows:

Vim ~/.bash_profile

(No tube. Bash_profile This file has a few, you can create a new one is also possible)

At the end add
Export ps1= ' [\[email protected]\h \w]\$ '

And then execute
SOURCE ~/.bash_profile

This way the shell can display the path.
