# UUIDGen
A real UUID generator and validator. Generate v4 UUIDs, batch-create multiple IDs, validate UUID format, extract UUIDs from text, and generate short 8-character IDs. Uses `/proc/sys/kernel/random/uuid` on Linux or falls back to `python3 uuid` module.
Commands
| Command | Description |
|---------|-------------|
| `uuidgen v4` | Generate a single random UUID v4 (with compact, uppercase, and URN formats) |
| `uuidgen batch <count>` | Generate multiple UUIDs (default: 5, max: 1000) |
| `uuidgen validate <uuid>` | Check if a string is a valid UUID (shows version, variant, and format details) |
| `uuidgen extract <text>` | Find and extract all UUIDs from a text string |
| `uuidgen short` | Generate a short 8-character UUID (plus 3 alternatives) |
| `uuidgen version` | Show version |
| `uuidgen help` | Show available commands and usage |
Requirements
When to Use
1. **Generate database keys** — `uuidgen v4` for a single ID, `uuidgen batch 100` for bulk
2. **Validate user-supplied UUIDs** — `uuidgen validate <uuid>` checks format, detects version and variant
3. **Extract IDs from logs/text** — `uuidgen extract "Error for session 550e8400-e29b-..."` pulls out all UUIDs
4. **Short identifiers** — `uuidgen short` for 8-char IDs suitable for URLs or display
5. **Batch ID generation** — `uuidgen batch 50` creates 50 UUIDs numbered for easy reference
Examples
# Generate a single UUID v4
uuidgen v4
# Generate 10 UUIDs
uuidgen batch 10
# Validate a UUID
uuidgen validate '550e8400-e29b-41d4-a716-446655440000'
# Extract UUIDs from text
uuidgen extract 'User 550e8400-e29b-41d4-a716-446655440000 created session abc12345-dead-beef-cafe-123456789012'
# Generate a short 8-char UUID
