上次用 WSL（Windows Subsystem for Linux）要追溯到好几年前了。当时 WSL 刚出来不久，抱着尝鲜的态度试着装了，想着万一能用，就不用装虚拟机了。
结果遇到了 BUG，就再也没用过。最近才听说 WSL2 已经有了，类似虚拟机的机制，好用很多。再次装来试试，目前还没遇到啥问题。记录下初始的美化步骤。
一、效果截图
天气、日历、数字时钟、Linux 发行版的 logo、系统信息

二、安装 WSL2 和 Windows Terminal
参考微软官方文档 Windows Subsystem for Linux Installation Guide for Windows 10
很详细，不用再看其他文章了。
三、oh-my-zsh
进入 wsl，安装 zsh：
sudo apt update
sudo apt install zsh -y
安装 oh-my-zsh：sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
安装 Powerline9k 主题：git clone https://github.com/bhilburn/powerlevel9k.git ~/.oh-my-zsh/custom/themes/powerlevel9k
启用 Powerline9k 主题：编辑 ~/.zshrc 配置文件，修改 ZSH_THEME 项的内容为 ZSH_THEME="powerlevel9k/powerlevel9k"
安装字体：访问 nerd-fonts 的 Github release 页，下载某种字体的压缩包（如 JetBrainsMono.zip），解压后在 Windows 系统上安装字体文件（有些时候可能需要使用管理员权限安装）
fonts
四、oh-my-zh 插件
安装 zsh-autosuggestions：
git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
安装 zsh-syntax-highlighting：
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
启用插件（包含默认插件）：修改 ~/.zshrc 配置文件的 plugins 项，内容如下（可按需添加或删减）
plugins=(
cargo
command-not-found
docker
git
golang
npm
nvm
rust
sudo
systemd
web-search
zsh-autosuggestions
zsh-syntax-highlighting
)
zsh-autosuggestions
插件安装完成后，如上图中的情况，直接按键盘上的右方向键即可自动补全命令。
五、neofetch 获取 Linux 发行版 ASCII logo 和系统信息
安装 neofetch：sudo apt install neofetch
效果如下：
$ neofetch --ascii_distro raspbian

neofetch --ascii_distro raspbian
neofetch 默认会输出当前系统的 logo，这里写个脚本（random_distro.sh）随机获取某个 Linux 发行版的 logo。
# random_distro.sh
distro_list=('Alpine' 'Anarchy' 'Android' 'Antergos' 'antiX' 'AOSC' 'ArcoLinux' 'ArchBox' 'ARCHlabs' 'ArchStrike' 'XFerience' 'ArchMerge' 'Arch' 'Artix' 'Arya' 'Bedrock' 'BlackArch' 'BLAG' 'BlankOn' 'BlueLight' 'bonsai' 'BSD' 'BunsenLabs' 'Calculate' 'Carbs' 'CentOS' 'Chakra' 'Chapeau' 'Chrom' 'Cleanjaro' 'ClearOS' 'Clear_Linux' 'Clover' 'Condres' 'Container_Linux' 'CRUX' 'Debian' 'Deepin' 'DesaOS' 'Devuan' 'DracOS' 'DragonFly' 'Drauger' 'Elementary' 'EndeavourOS' 'Endless' 'Exherbo' 'Fedora' 'Feren' 'FreeBSD' 'FreeMiNT' 'Frugalware' 'Funtoo' 'GalliumOS' 'Gentoo' 'Pentoo' 'GNU' 'GoboLinux' 'Grombyang' 'Guix' 'Haiku' 'Huayra' 'Hyperbola' 'janus' 'Kali' 'KaOS' 'KDE_neon' 'Kogaion' 'Korora' 'KSLinux' 'Kubuntu' 'LEDE' 'LFS' 'Linux_Lite' 'LMDE' 'Lubuntu' 'Lunar' 'macos' 'Mageia' 'Mandriva' 'Manjaro' 'Maui' 'Mer' 'Minix' 'LinuxMint' 'MX_Linux' 'Namib' 'Neptune' 'NetBSD' 'Netrunner' 'NixOS' 'Nurunner' 'NuTyX' 'OBRevenge' 'OpenBSD' 'OpenIndiana' 'OpenMandriva' 'OpenWrt' 'osmc' 'Oracle' 'Parabola' 'Pardus' 'Parrot' 'Parsix' 'TrueOS' 'PCLinuxOS' 'Peppermint' 'popos' 'Porteus' 'PostMarketOS' 'Puppy' 'PureOS' 'Qubes' 'Radix' 'Raspbian' 'Reborn_OS' 'Redstar' 'Redcore' 'Redhat' 'Refracted_Devuan' 'Rosa' 'sabotage' 'Sabayon' 'Sailfish' 'SalentOS' 'Scientific' 'Septor' 'SharkLinux' 'Siduction' 'SliTaz' 'SmartOS' 'Solus' 'Source_Mage' 'Sparky' 'Star' 'SteamOS' 'SunOS' 'openSUSE_Leap' 'openSUSE' 'SwagArch' 'Tails' 'Trisquel' 'Ubuntu-Budgie' 'Ubuntu-GNOME' 'Ubuntu-MATE' 'Ubuntu-Studio' 'Void' 'Obarun' 'windows10' 'Windows7' 'Xubuntu')
length=${#distro_list[@]}
distro=${distro_list[$RANDOM % $length]}
neofetch --ascii_distro $distro
运行 bash random_distro.sh 即可获取随机的 Linux 发行版 logo。
为了使该脚本可以在 Terminal 启动时自动运行，可以添加如下一条命令到 ~/.zshrc 配置文件末尾：
bash /path/to/random_distro.sh
六、Shell 脚本显示天气和数字时钟
weather-clock.sh 脚本从网上找的，没做改动（参考文章 Terminal splash screen with Weather, Calendar, Time & Sysinfo?）。代码如下：
#!/bin/bash
# NAME: now
# PATH: $HOME/bin
# DESC: Display current weather, calendar and time
# CALL: Called from terminal or ~/.bashrc
# DATE: Apr 6, 2017. Modified: May 24, 2019.
# UPDT: 2019-05-24 If Weather unavailable nicely formatted error message.
# NOTE: To display all available toilet fonts use this one-liner:
# for i in ${TOILET_FONT_PATH:=/usr/share/figlet}/*.{t,f}lf; do j=${i##*/}; toilet -d "${i%/*}" -f "$j" "${j%.*}"; done
# Setup for 92 character wide terminal
DateColumn=34 # Default is 27 for 80 character line, 34 for 92 character line
TimeColumn=61 # Default is 49 for " " " " 61 " " " "
# Replace Edmonton with your city name, GPS, etc. See: curl wttr.in/:help
curl wttr.in/Hangzhou?0 --silent --max-time 3 > /tmp/now-weather
# Timeout #. Increase for slow connection---^
readarray aWeather < /tmp/now-weather
rm -f /tmp/now-weather
# Was valid weather report found or an error message?
if [[ "${aWeather[0]}" == "Weather report:"* ]] ; then
WeatherSuccess=true
echo "${aWeather[@]}"
else
WeatherSuccess=false
echo "+============================+"
echo "| Weather unavailable now!!! |"
echo "| Check reason with command: |"
echo "| |"
echo "| curl wttr.in/Edmonton?0 |" # Replace Edmonton with your city
echo "| --silent --max-time 3 |"

运行效果：
$ bash weather-clock.sh

weather-clock
其中获取天气的关键代码为 curl wttr.in/Hangzhou?0 --silent --max-time 3，可自行改为自己所在的城市。
同样，为了使 Terminal 在启动时能自动运行该脚本，在 ~/.zshrc 配置文件的末尾（random-distro.sh 上面一行）添加如下内容：
bash /path/to/weather-clock.sh
PS：数字时钟的正常显示需要依赖 toilet 软件。
安装 toilet：sudo apt install toilet
七、pipe.sh 生成 Terminal 启动动画
获取 pipe.sh 程序：git clone https://github.com/pipeseroni/pipes.sh.git
提取项目中的 pipes.sh/pipes.sh 源文件到任意路径下。
为了使 Terminal 在启动时能自动运行该脚本，在 ~/.zshrc 配置文件的末尾（weather-clock.sh 上面一行）添加如下内容：
bash /path/to/pipes.sh -p 5
pipes.sh
按下空格键可终止动画。
