uptime Command Generator

## What is uptime?

The `uptime` command shows how long the system has been running, the current time, the number of logged-in users, and the 1/5/15-minute load averages. It's a quick one-liner health check for any server.

## How to Use

1. **Run Plain**: With no options, `uptime` prints the default one-line summary. 2. **Pick a Format (optional)**: Use `-p` for a human-friendly duration or `-s` for the exact boot timestamp. 3. **Copy & Run**: Copy the generated command into your terminal.

### `-p` Pretty format Print the duration as a friendly phrase like `up 2 weeks, 3 days, 4 hours, 5 minutes` — easy to read in scripts or status pages. Omits time, users, and load averages.

### `-s` Boot time Print the system's boot timestamp (e.g. `2024-06-15 10:30:45). Useful for correlating with logs or checking when a machine last rebooted.

### Default output (no flags) The one-line form: current time, uptime duration, user count, and the three load averages. Best for a quick at-a-glance check.
