新机器 Flow

1. 换源（不是国内机器则跳过）

   • 更新源
   • 更新软件包或滚包（Arch 系列）

2. 下载 proxychains 代理（如果没有网络业障则跳过）

   • 配置 proxychains

3. 更新 dotfiles

# 推荐 MIT 老师 Anish 的 dotfiles 一键配置
cd ~
# 如果是 WSL2，先要打开代理软件的 Allow LAN
proxychains git clone https://github.com/anishathalye/dotfiles
cd dotfiles && proxychains ./install

4. 半自动 bash script

git config --global user.name "TinySnow"
git config --global user.email "lo.tinysnow.ol@outlook.com"

# 消除 `-bash: hostname: command not found` 提示
sudo pacman -S inetutils

cd ~
rm -rf .bashrc .bash_profile
git clone https://github.com/anishathalye/dotfiles.git && cd dotfiles
./install

cd ~

cd ~

# 以下手动操作
vim ~/.bin/gib.sh
vim ~/.bin/prepare.sh
# 添加 ssh 私钥
vim ~/.ssh/id_rsa
# 更改私钥的权限
chmod 700 ~/.ssh/id_rsa
