• 简洁性（30%）：避免冗余命令，逻辑清晰。
• 创新性（30%）：组合方式是否突破常规思维。

往届优秀案例

• 日志实时监控：tail -f logfile | grep --color "ERROR" | awk '{print $1, $3}'
• 批量重命名：ls *.jpg | awk '{print "mv "$1" "substr($1,1,4)"_new.jpg"}' | bash

技术文章结构建议

• 问题场景：描述具体痛点（如海量文件分类）。
• 传统解法：列出常规命令及其局限性。
• 创新方案：分步骤拆解组合命令，解释管道逻辑。
• 效果验证：通过时间统计或代码量对比证明优势。

参赛资源推荐

• 官方文档：GNU Coreutils、Linux Man Pages。
• 工具链：time命令测速、script记录操作过程。

大赛流程与奖项

• 初赛（提交方案）→复赛（线上演示）→决赛（评委现场挑战）。
• 奖项设置：最佳效率奖、极客创意奖、社区人气奖。

技术写作技巧

• 使用代码块高亮关键命令，例如：

  find /path -type f -mtime +30 -exec rm {} \;

• 配图建议：终端截图对比传统与创新方法的输出结果差异。

常见问题解答

• 如何避免复杂命令的调试风险？建议先用echo预览生成结果再执行。
• 多命令组合的性能瓶颈？可通过xargs并行处理优化。
