Quick UUID

Generate UUIDs (v4) and short random IDs from the command line. Use when you need a unique identifier for files, records, test fixtures, or correlation IDs and want a zero-dependency one-liner.

A tiny helper for generating unique identifiers without extra dependencies.

Generate a UUID v4

# Linux (kernel-provided)
cat /proc/sys/kernel/random/uuid

# Portable (Python, always available with OpenClaw runtimes)
python3 -c "import uuid; print(uuid.uuid4())"

Generate a short random ID (8 chars, url-safe)

python3 -c "import secrets; print(secrets.token_urlsafe(6))"

Generate several at once

python3 -c "import uuid;[print(uuid.uuid4()) for _ in range(5)]"

Notes

• UUID v4 is random; collision probability is negligible for practical use.
• Prefer secrets over random for anything security-adjacent.
• Short IDs are convenient for logs/correlation but are NOT collision-proof at scale.
