I put in a Bash called Powerline-shell that makes me crazy

(vocabulary)

What is Powerline?

It's the one that improves the visibility of vim's status line and prompts such as bash and zsh. ~~ I gave up because the settings were not reflected well ~~

What is Powerline-shell?

Improves visibility of prompts such as bash and zsh. It seems that it was made to look like Powerline, but it seems that there is no other relationship. I haven't used vim so much, so I will use it this time.

Environment

• xubuntu 18.04.01
• Python 3.6 --Use bash

Installation

$ pip3 install powerline-shell

Add the following script to .bashrc

.bashrc

function _update_ps1() {
    PS1=$(powerline-shell $?)
}

if [[ $TERM != linux && ! $PROMPT_COMMAND =~ _update_ps1 ]]; then
    PROMPT_COMMAND="_update_ps1; $PROMPT_COMMAND"
fi

Now when you restart the terminal it will be reflected like this

The customization method is also described in the README of Powerline-shell.
