Create Command

# Create a Terminal Command or Shell Script

You are a senior DevOps engineer and Linux/Unix systems expert. Generate the precise command or script needed for my task.

## Task Details
- **What I Need to Do:** [TASK_DESCRIPTION]
- **Operating System:** [OS] (e.g., Ubuntu 22.04, macOS Ventura, Windows PowerShell, Alpine Linux)
- **Shell:** [SHELL] (e.g., bash, zsh, sh, PowerShell, fish)
- **Context:** [CONTEXT] (e.g., local development, production server, Docker container, CI/CD pipeline)
- **My Skill Level:** [LEVEL] (beginner / intermediate / advanced)
- **Any Constraints:** [CONSTRAINTS] (e.g., no sudo access, must run as cron job, must be idempotent)

## Deliverables

### The Command
```bash
[EXACT_COMMAND_OR_SCRIPT]
```

### What This Command Does (Plain Language)
Step-by-step explanation of what each part of the command does — no assumptions that I know the flags.

### Flags and Arguments Explained
| Flag/Argument | Meaning | Why Used Here |
|---|---|---|
| [FLAG_1] | [EXPLANATION] | [REASON] |
| [FLAG_2] | [EXPLANATION] | [REASON] |

### How to Run It
- Prerequisites to install or check first
- Exact steps to execute
- Expected output when it works correctly

### Error Handling
- Most common errors this command produces and what they mean
- How to fix each error
- Safe way to test the command before running on production

### Variations
Provide 3 variations of the command for slightly different scenarios:
1. [VARIATION_1]: [WHEN_TO_USE]
2. [VARIATION_2]: [WHEN_TO_USE]
3. [VARIATION_3]: [WHEN_TO_USE]

### If This Is a Multi-Step Process
Write a complete shell script that:
- Includes error checking (`set -e`, `set -u`)
- Has comments explaining each section
- Logs what it is doing
- Is idempotent (safe to run multiple times)

### Security Notes
- Any security implications of running this command
- Whether root/sudo is necessary and how to minimize privilege
- Data you should back up before running

Make the output beginner-friendly for [LEVEL] users while keeping it technically precise.
