<sxh bash; gutter: false>
  sudo vim /etc/bash.bashrc

if [ -f `which powerline-daemon` ]; then
    powerline-daemon -q

# When it comes to choosing a font for powerline, I recommend firstly previewing them in an application called font-manager
  sudo apt install font-manager
==== Vim ====
  sudo vim /etc/vim/vimrc.local
<sxh bash; gutter: false>
set  rtp+=/usr/local/lib/python2.7/site-packages/powerline/bindings/vim/
set laststatus=2
set t_Co=256
</sxh>

In the Terminal app, select your font. Seem I like Noto Mono for Powerline Regular size 10

#  powerline-config tmux setup
  vim ./.tmux.conf 
<sxh bash; gutter: false>
source /usr/local/lib/python3.7/dist-packages/powerline/bindings/tmux/powerline.conf
set-option -g default-terminal "screen-256color"
</sxh> 

  tmux source-file ~/.tmux.conf  # Run this after you changed your color settings for it to update
  tmux kill-server # You need to restart tmux entirely after changing .tmux.conf.
