jps-crontab-utils

Collection of Python utilities for parsing, validating, and searching crontab files.

🚀 Overview

jps-crontab-utils provides three command-line tools:

1. Crontab Parser

Parses raw crontab files into structured job objects:

• Supports per-job metadata via comment blocks
• Handles multiline commands with POSIX \ continuation
• Resolves executables using $PATH or absolute paths
• Normalizes metadata keys automatically (owner-email → owner_email)

2. Crontab Checker

Validates each cron job for:

• Required metadata (owner, owner email, reference, repository, etc.)
• Recommended metadata (labels, run frequency, description, etc.)
• Executable existence, file type, +x bit, and non-empty status
• Outputs human-readable tables or JSON for automation

3. Crontab Search Utility

Queries crontab entries based on:

• Labels (--label nightly)
• Owner email (--email john.smith)
• Code repository (--repo [e-mail]:org/pipeline.git)
• Full JSON output for programmatic analysis

These utilities help improve crontab hygiene, enforce team standards, and identify broken or undocumented jobs across large environments.
