Bash 与系统命令规范

参考来源: Google Shell Style Guide


🚫 严格禁止

1. 禁止行尾注释

  • ❌ curl -X POST ... # 发送请求
  • ✅ 注释必须独占一行,放在代码上方

2. 禁止隐式路径

  • ❌ rm test.txt
  • ✅ 优先使用变量或绝对路径:rm "${WORK_DIR}/test.txt"

🛠️ 脚本编写原则

  • 防御性头声明:所有 .sh 文件首行必须包含 set -euo pipefail。
  • 变量引用:必须为所有变量引用加双引号("${VAR}"),防止空格溢出。
  • 安全写入:禁止在大段脚本中使用 cat <<EOF > file。优先使用 write_file (工具) 或分步 tee 写入。
# ✅ 良好的脚本头
#!/usr/bin/env bash
set -euo pipefail

💻 命令输出与日志

  • 复杂命令必须使用 tee -a "${LOG_FILE}" 同时记录到屏幕和日志。
  • 循环操作必须打印当前进度索引(如 [1/50] Processing...)。

📋 本回复遵循:bash-style - [章节]
