Zsh一站式初始化脚本

这份脚本适合做一轮最常用的 Zsh 环境初始化：

• 安装 Oh My Zsh
• 安装 zsh-autosuggestions
• 安装 zsh-syntax-highlighting
• 修改主题和插件配置

脚本

#!/bin/zsh
 
retry_command() {
  local cmd="$1"
  local retries=3
  local count=0
 
  while ((count < retries)); do
    eval "$cmd" && return 0
    count=$((count + 1))
    echo "Attempt $count/$retries failed. Retrying..."
    sleep 2
  done
 
  echo "Command failed after $retries attempts: $cmd"
  exit 1
}
 
detect_os() {
  if [[ "$OSTYPE" == "darwin"* ]]; then
    echo "macos"
  elif [[ "$OSTYPE" == "linux-gnu"* ]]; then
    echo "linux"
  else
    echo "unknown"
  fi
}
 
main() {
  retry_command 'RUNZSH=no sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"'
  retry_command 'git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions'
  retry_command 'git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting'
 
  local os_type=$(detect_os)
  if [[ "$os_type" == "macos" ]]; then
    sed -i '' -e 's/ZSH_THEME="robbyrussell"/ZSH_THEME="ys"/g' \
      -e 's/plugins=(git)/plugins=(z sudo git zsh-autosuggestions zsh-syntax-highlighting)/g' \
      "$HOME/.zshrc"
  else
    sed -i -e 's/ZSH_THEME="robbyrussell"/ZSH_THEME="ys"/g' \
      -e 's/plugins=(git)/plugins=(z sudo git zsh-autosuggestions zsh-syntax-highlighting)/g' \
      "$HOME/.zshrc"
  fi
}
 
main

注意

这份脚本默认 ~/.zshrc 里已有 Oh My Zsh 默认生成的那一行 plugins=(git)，否则替换命令不会命中。
