## Overview / 概览

• Preview next 100 run times instantly / 即时预览未来100次执行时间，精准掌控任务排期
• Detect overlapping jobs across multiple cron expressions / 智能检测多个表达式间的任务重叠，避免资源冲突
• Visual timeline chart for schedule analysis / 可视化时间线图表，让调度模式一目了然
• Human-readable translation of complex expressions / 将复杂表达式翻译成易懂的自然语言描述
• Bulk validation of cron syntax with error pinpointing (Pro) / 批量验证Cron语法并精准定位错误（Pro专属）
• Auto-optimize schedules to avoid peak hours and conflicts (Pro) / 自动优化调度策略，避开高峰时段与冲突（Pro专属）

## How It Works / 原理

```bash
# Step 1 — check environment
which bash curl && echo "Ready"

# Step 2 — run the tool
cron-debug "*/15 * * * 1-5" --next 5 --timeline Shows next 5 run times and timeline for a weekday-every-15-minutes cron job / 展示工作日每15分钟运行的计划，含下次执行时间与时间线 

# Step 3 — review output
echo "Done — check the generated output"
```

## Example Scenarios / 示例场景

• Debugging a misconfigured nightly backup job that runs twice instead of once / 夜间备份任务因配置错误重复执行，快速定位并修复调度冲突
• Validating a suite of cron jobs before deploying to production / 部署上线前批量校验所有Cron表达式，确保生产环境零事故
• Explaining complex schedules to non-technical team members during planning / 向非技术人员直观解释复杂调度逻辑，提升团队协作效率
