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 - Bash 4+ (`set -euo pipefail`) - One of: `/proc/sys/kernel/random/uuid` (Linux), `python3`, or `/dev/urandom` - No external dependencies or API keys ## 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 ```bash # Generate a single UUID v4 uuidgen v4 # Generate 10 UUIDs uuidgen batch 10 # Validate a UUID uuidgen validate [REDACTED_SECRET] # 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 uuidgen short ``` ### Example Output ``` $ uuidgen v4 ┌──────────────────────────────────────────────────┐ │ UUID v4 Generated │ ├──────────────────────────────────────────────────┤ │ UUID: 1a28540e-25e6-4efe-86a8-93f41e16dad8 │ │ Compact: 1a28540e25e64efe86a893f41e16dad8 │ │ Upper: 1A28540E-25E6-4EFE-86A8-93F41E16DAD8 │ │ URN: urn:uuid:1a28540e-25e6-4efe-86a8-... │ └──────────────────────────────────────────────────┘ $ uuidgen validate [REDACTED_SECRET] ┌──────────────────────────────────────────────────┐ │ UUID Validation │ ├──────────────────────────────────────────────────┤ │ Input: 550e8400-e29b-41d4-a716-446655440000 │ │ Valid: ✅ YES │ │ Version: v4 (random) │ │ Variant: RFC 4122 / DCE │ │ Compact: 550e8400e29b41d4a716446655440000 │ └──────────────────────────────────────────────────┘ $ uuidgen batch 3 ═══════════════════════════════════════════════════════ Generating 3 UUIDs ═══════════════════════════════════════════════════════ 1. b54a201e-47d7-463e-9539-86e08201b4f0 2. 7fa328ef-fba4-4a7a-94c2-2dc431079aae 3. 0d382fb3-0c52-424b-a7cd-416f6c29ad49 Generated 3 UUID(s). ``` --- *Powered by BytesAgain | bytesagain.com | [REDACTED_SECRET]*
