1. 简介
Powerline 是个终端状态线的插件, 可以为 bash, vim, zsh, tmux, ipython 等终端编辑和终端命令工具提供丰富的状态线显示.
2. 安装 powerline-status
参考: Github
- 在 Ubuntu 20.04 系统下可以使用 pip3 来安装:
1
sudo pip3 install powerline-status
- 获取文件的安装位置, 与所使用的 python3 版本有关
1
2
powerline_location=$(/usr/bin/pip3 show powerline-status \
| grep -Po "(?<=Location: ).*(?=$)") && echo $powerline_location
- 把相关的配置文件复制到用户目录下, 方便修改

mkdir -p ~/.config/powerline/colorthemes
mkdir -p ~/.config/powerline/themes/shell
cp $powerline_location/powerline/config_files/config.json ~/.config/powerline/
- 为终端启用 Powerline
自行把下面的 <powerline_location> 修改为上面获得的路径的值.
把以下内容填入 ~/.bashrc 的末尾:

3
if [ -f <powerline_location>/powerline/bindings/bash/powerline.sh ]; then
source <powerline_location>/powerline/bindings/bash/powerline.sh
fi
